An overbite might not seem like a serious condition for your dog, but severely misaligned teeth can lead to difficulty eating, gum injuries and bruising, bad breath and different types of dental problems, including tooth decay and gingivitis. Fortunately, there are ways to help fix the problem before it becomes irreversible.

An overbite is a genetic, hereditary condition where a dog"s lower jaw is significantly shorter than its upper jaw. This can also be called an overshot jaw, overjet, parrot mouth, class 2 malocclusion or mandibular brachynathism, but the result is the same – the dog"s teeth aren"t aligning properly. In time, the teeth can become improperly locked together as the dog bites, creating even more severe crookedness as the jaw cannot grow appropriately.

This problem is especially common in breeds with narrow, pointed muzzles, such as collies, shelties, dachshunds, German shepherds, Russian wolfhounds and any crossbred dogs that include these ancestries.

Small overbites often correct themselves as the puppy matures, and brushing the dog"s teeth regularly to prevent buildup can help keep the overbite from becoming more severe. If the dog is showing signs of an overbite, it is best to avoid any tug-of-war games that can put additional strain and stress on the jaw and could exacerbate the deformation.

If an overbite is more severe, dental intervention may be necessary to correct the misalignment. While this is not necessary for cosmetic reasons – a small overbite may look unsightly, but does not affect the dog and invasive corrective procedures would be more stressful than beneficial – in severe cases, a veterinarian may recommend intervention. There are spacers, braces and other orthodontic accessories that can be applied to a dog"s teeth to help correct an overbite. Because dogs" mouths grow more quickly than humans, these accessories may only be needed for a few weeks or months, though in extreme cases they may be necessary for up to two years.

If the dog is young enough, however, tooth extraction is generally preferred to correct an overbite. Puppies have baby teeth, and if those teeth are misaligned, removing them can loosen the jaw and provide space for it to grow properly and realign itself before the adult teeth come in. Proper extraction will not harm those adult teeth, but the puppy"s mouth will be tender after the procedure and because they will have fewer teeth for several weeks or months until their adult teeth have emerged, some dietary changes and softer foods may be necessary.

An overbite might be disconcerting for both you and your dog, but with proper care and treatment, it can be minimized or completely corrected and your dog"s dental health will be preserved.

I recently received two emails from police K9 handlers who had similar tracking problems. Both had dogs that ran tracks but blew by the corners. They both wanted to know what to do. The following is what I recommended.

There is nothing wrong with a dog running on a track as long as the dog has scent. In fact, in many cases, unless the dog can track at a run, they will never catch up to the suspect.

Bottom line is: dogs that run when tracking catch more bad guys than foot-step-trackers. By foot-step-trackers I mean the style of tracking seen in Schutzhund or IPO.

Dogs that run will almost always overshoot corners. It"s about impossible not to. With experience, a well-trained dog will give a noticeable track-loss indication and start to circle. This must become a trained reaction for track loss.

Our goal is to teach the dog to give a clear signal for track loss when they overrun a corner. It"s the handler"s responsibility to recognize that signal. This should be something that is learned on training tracks.

When handlers recognize track-loss within 20 to 30 feet past a corner, the handler can help the dog (through circling) figure out which way the suspect went. Brand new police service dogs can be taught track-loss in at 50 training tracks. Dogs that have problems because of a poor foundation in tracking may need 150 to 200 tracks. Bottom line is it"s always quicker to train a behavior correctly from the beginning than having to go back and retrain a problem out of the dog.

Handlers must also lay their own tracks for this work and those tracks need to be laid INTO THE WIND. They have to know exactly where the corners are. They also need to know when a dog overshoots the corner, it 100% does not have any track scent. By tracking into the wind you know this.

Most K9 handlers know that they need to kick in the corner, usually 3 or 4 feet before and 3 or 4 feet after each corner. That way the odor cone is always stronger at the corner. Some dog"s pick this up quickly and take corners on their own.

When that happens, the trainer stops kicking in the corners. They may fade to only kicking 3 or 4 feet after the corner and then after a number of training tracks, they fade it altogether. This may be the point when some dogs have corner problems because they have been waiting for the stronger "odor cone," and when it doesn"t come, they blow right on past the corner.

When the dog blows a corner, the handler needs to really focus and watch his dog"s head. You know there is no scent there because of the wind direction. In the beginning, the handler stops on the corner and lets the dog work out the problems.

If the dog continues to hunt for the track, have patience and let him. If he wants to pull straight ahead, don"t go with him. If the track goes to the right and he wants to go left, don"t go with him, just hold the leash and let him run in a circle to the left and bring him around until he cuts the track going to the right. Should the dog cut the first leg and want to track to the corner again, let him. It"s part of the learning experience.

One of the things an experienced dog handler will talk about is the head snap when his dog cuts a track. That happens when the dog is moving pretty quickly and he cuts across a track.

Handlers can actually teach head-snaps by not going to the exact beginning spot where they laid their training track. Rather, have the dog run in a circle and cut the track 5 or 10 yards down the first leg. Most of the time, a K9 handler never knows exactly where the track started. In addition, by the time he or she gets there, other officers have trampled the scene. So the K9 handler is forced to go beyond the contamination and cut the track.

So back to corners. Our goal is to teach our dog that when it gets track loss, it circles to cut the track after a corner. If the handler has worked a head-snap on his "starts", this will be easier for the dog and handler at corners.

As long as the dog is working, handlers should remain quiet at a track-loss. If the dog is searching giving multiple "FIND IT" commands does nothing other than make the dog nervous.

In the beginning, don"t be too concerned if the dog struggles. As long as you know exactly where the corner is, you are in control. The natural tendency is to help the dog. Handlers that help by pointing out the corner end up with a dog that gets in trouble and expects the handler to show him where to go. So your goal is for your dog to become a problem solver.

If the dog wants to pull past the corner in the direction of the first leg, don"t go with him. Stand your ground. This becomes a subtle statement for the dog. You"re not showing him which way the track goes, but you are telling him that you know he can"t smell it (because you"re going into the wind). Your goal is to teach him to work out the problem of "WHERE DID THE TRACK GO?"

So when the dog lifts his head, quietly ask him to "find it". See if he has the drive to look on his own. Let him struggle a little. That"s how he learns.

If he flat stops, then you have to circle and cut the track. When we lay tracks we use articles. We will always leave an article 30 to 40 feet after a corner. This is a subtle way of rewarding a dog after a corner.

How you handle the dog when you stop at corners is important. I would use my voice to ASK HIM to look, not COMMAND him to look. Encourage the dog to find the track but not to the point of distraction. Too much from you and you become the problem.

Just remember that your goal during this period is not to get to the end of the track but for you to learn your dogs "track-loss indication" and for the dog to learn to circle when it overshots the corners.

These training tracks (into the wind) need to continue until the handler feels confident in recognizing a track-loss signal from his dog. Once that happens he can change things up. Tracks can be laid with the wind at your back and when that"s good the handler needs to move on to "unknown tracks".

If you want to learn more about Police K9 tracking (or Search & Rescue Tracking), I recommend that you get the set of DVDs or future online courses that I did with the Royal Canadian Mounted Police. The RCMP are hands-down the best tracking dog trainers in North American and even in the world.

Ed Frawley is the founder of Leerburg. He has been training dogs since the 1950s. For 30 years, Ed bred working bloodline German Shepherds and has produced over 350 litters. During this time, Ed began recording dog training videos and soon grew an interest in police service dogs. His narcotic dogs have been involved in over 1,000 narcotics searches resulting in hundreds of arrests in the state of Wisconsin. Ed now solely focuses on producing dog training courses with renowned dog trainers nationwide. If you want to learn more about Ed, read about his history here.

Boart Longyear’s New Overshot Resolving Pointy IssuesSince Boart Longyear introduced the Q™ Wireline system in 1966, retrieving the inner tube from the core barrel has been handled the same way: an overshot with lifting dogs (spring loaded hooked “fingers”) is lowered or pumped into the hole until it snaps over a pivoting spearhead mechanism affixed to the inner tube assembly. Once the head assembly has been removed from the hole, the driller uses the pivoting spearhead to position the head assembly on their workspace and squeezes the back of the lifting dogs to release.In all this time, this system (seen in photo on the right) has had the same basic issues:

Lifting Dog and Spearhead Wear: To balance strength and wear resistance, lifting dogs and spear points are heat treated to a medium hardness. However, it’s difficult to visually evaluate or functionally test the degree of wear, especially in underground applications.

Boart Longyear currently provides a secondary safety pin that clips through the overshot, passing just under the spearhead tip. This adds an extra layer of protection in case the lifting dogs are excessively worn or deformed. However, spearheads are loaded cyclically and often loaded ‘off-pivot’, which deforms the components over time, to the point of disassembly. While the more recent MKII™ version of the spearhead assembly is much more robust, in the case of spearhead failure, the head assembly will release from the overshot regardless of lifting dog or safety pin use or condition.

This patent-pending overshot leverages our previous experience with Roller Latch™ head assemblies to create a more reliable and longer lasting system that eliminates spearheads and lifting dogs entirely. The spearhead assembly is replaced by a one-piece socket receptacle (spearhead adapter) that accepts the overshot itself, which has rollers that latch into an internal groove in the spearhead adapter.

The increased toughness and hardness of the bearing quality latch rollers have a proven history of outlasting traditional pivoting latches for wear life. The new overshot will also feature the same Nitreg™-ONC surface treatment as Roller Latch head assemblies that drastically improves corrosion resistance (Nitreg is a trademark of Nitrex Inc.).Safety pin integration in the new underground Quick Pump-In™ overshot now pulls double duty of both locking the overshot from accidentally releasing while hoisting, as well as holding the head assembly and overshot together in case of component failure due to excessive wear. Also, the socket and rollers are not affected by side loading and ‘off-pivot’ loading during tube handling outside the hole, eliminating gradual deformation or disassembly. The new surface overshot will also include a one-hand twist-lock sleeve to maintain a locked position while hoisting outside the hole, even with a loss of wireline cable tension.It’s also easy to use. Instead of pushing the backs of the lifting dogs together, the driller pushes the two halves of the assembly together, retracting the rollers and releasing the head assembly. This operation takes about the same amount of force as the current overshot, so drillers won’t miss a beat.

Additional benefits have been included[CA1] apart from the elimination of the spearhead and lifting dogs. While the current design uses a solid pivot pin that is peened into place (making it difficult to re-build), the Roller Latch Overshot has no pins whatsoever. Everything is held in place by simple threaded connections for easy maintenance.The Quick Pump-In™ (Q/P, underground) assembly further addresses two issues specific to pump-in applications

The Roller Latch Overshot features a brand new pump-in cable release system, originally conceptualized and prototyped by one of our expert underground drillers in Canada. A slotted sleeve and pumping seal assembly is placed over the wireline and pumped up to the overshot. The sleeve engages a quick-release mechanism and releases the wireline. This system has proven to be much more reliable, and may be the feature drillers are most thrilled to have going forward. Reports of fewer broken wirelines have been received from several sites testing the pump-in cable release system.

To combat this and make Q/P Roller Latch easier to use while maintaining its safety features, a ‘brake release spring’ was created. This spring assembles quickly inside of the spearhead adapter on the head assembly. While tripping on its own, the head assembly brake works normally, but when the overshot latches into it this spring is compressed, disengaging the brake. This feature has also been received very positively by drillers in the field.

A surface-style overshot is also in development in B/N/H sizes. In addition to many of the features outlined in this article, the aim is to add more innovations, including:

• An improved lock sleeve to disable accidental head assembly release and stop drillers from accidentally sending the overshot down the hole while locked.

The Series 10 Sucker Rod Overshot is a small, rugged tool designed for engaging and retrieving sucker rods, couplings, and other items from inside tubing strings.

Series 20 Short Catch Sucker Rod Overshots are designed for conditions when sucker rods, couplings, and other portions of a fish are too short for retrieval with a standard overshot.

The Hydraulic Release Overshot was designed to aid in the recovery of a stuck fish in a horizontal drilling application where normal rotation for release is not obtainable.

The Series 150 Releasing and Circulating Overshot consists of three main external parts: a Top Sub, a Bowl, and a Guide. Internal catch and pack-off parts are determined by the diameter of the fish. Each assembly is designed for a maximum catch diameter.

A Series 160 Side Door Overshot is recommended when fishing for cable tools or conductor lines in cased holes. The side door overshot is run in on tubing or drill pipe.

Externally engage, pack off, and pull a fish with our wide range of overshot tools. The first fishing choice when screwing into the fish is not an option, our overshot tools are simply designed but ruggedly built. Choose from options including:

Kelo socket overshots are proven to catch small-diameter workstrings and sucker rods inside casing as well as recover coiled tubing that has parted and remains in hole.

The t-dog, mouse-trap, and flipper-dog (TMF) overshot can be dressed in three different ways for different washover applications. Deploy the t-dog assembly option to washover and recover mud-stuck or sanded-up square-collared pipe in one trip. Use the mouse-trap assembly to catch sucker rods, integral joint tubing, or cables. And with the flipper-dog assembly, you can confidently catch a fish with different ODs.

Persistently improving certain performance characteristics of products, like functionality, reliability or usability, may make for difficulties in consuming those products, which is the situation of overshooting (Christensen, 1997; Chen, Reilly and Lynn, 2012; Lukas et al., 2013). Overshot customers may consider products as too complex to use, too expensive to buy, too functionally advanced, or too good to have(Christensen, 1997; Thompson, Hamilton and Rust, 2005; Lukas et al., 2013). Prior researchers take overshooting seriously for it may give opportunities to disruptive innovations from the low-end market of the overshooting products (Christensen, 1997; Schmidt and Druehl, 2008b; Hang, Garnsey and Ruan, 2015a; Christensen et al., 2018).

However, it is against our common sense that people would be overshot by getting too much of a good thing. Many disruptive innovations" successful disruption over incumbent products, like microscope surgery’s disruption over traditional surgery, are not because incumbent products are too good for customers (Klenner, Hüsig and Dowling, 2013; King and Baatartogtokh, 2015; Zhang, 2015). Moreover, people with intensive demand on certain product performances, like high-end customers, should be hardly satiated by product performance improvement. However, high-end disruptions are still existent and consequent to
