Experienced and professional animal trainer provide their insights in answering this question :
A. Puppies chew out of boredom, when playing and during teething. As an owner, it is up to you to teach what is appropriate chewing and what is not. Always provide appropriate chew toys for your breed/size of dog. Correct him/her when chewing inappropriately (either the wrong item or too rough). Praise and reward your pup when he/she chews appropriately. If he/she gets too riled up during play, avoid those actions that bring it to that point. A trainer can assist you in teaching the “No bite” command and other basic commands.

Either ignore him for 10 to 20 seconds or, if he starts mouthing on you again, get up and move away for 10 to 20 seconds. If necessary, leave the room. After the short time-out, return to your dog and encourage him to play with you again. It`s important to teach him that gentle play continues, but painful play stops.
The good news: in the vast majority of cases, puppy biting and mouthing is EXTREMELY normal, for several reasons: Puppies explore the world with their mouths. They go through an uncomfortable teething process that lasts for 2-3 months.
Many dogs will put their mouth and paw on us – not with any intention to hurt, but more to attract play and affection. This is known as mouthing and pawing. This most commonly occurs with puppies, but often continues into adulthood.
Instead of reacting to your puppy mouthing, try to redirect their attention somewhere else, like a favourite toy. It can be tempting to encourage them to play with your hands or clothes, but while it might be cute when they`re small, this will become a problem when your puppy gets bigger.
Adolescent and adult dogs who exhibit mouthy behavior tend to also be social, energetic, playful, and outgoing. These dogs typically jump up and grab people`s clothing or limbs with their mouths when they are feeling frustrated, excited, or seeking attention.
Puppy discipline uses a combination of redirection, basic commands that reprimand in a firm but calm tone of voice, supervision, and positive reinforcement. Positive reinforcement: When puppies exhibit good behavior or correct bad behavior, reward them with verbal praise, petting, treats, or playtime.
Affection – Licking is a sign of affection. Your dog might lick your hands and face because they love you! Licking might feel good to your dog as it can release endorphins. Some experts also say that in addition to affection, licking is a sign of submission.
3) If the aggressor dog does not release the bite grip when pulled by his tail, grab his back legs and flip him on his back. 95% of the dogs will release a bite grip when flipped on the back. It is very important that this is done correctly so that the action is safe and effective.
When your dog licks your hand, it`s a sign of submission to you as the leader of their pack, and eases the stress of separation anxiety if you`ve been absent. Licking your hand is typical canine behaviour that has its origins all the way back when dogs evolved from wolves in the wild.
Either ignore him for 10 to 20 seconds or, if he starts mouthing on you again, get up and move away for 10 to 20 seconds. After the short time-out, return to your puppy and encourage him to play with you again. It`s important to teach him that gentle play continues, but painful play stops.
Most puppies start teething at around 2 or 3 months of age and stop between 5 to 8 months, when all of their adult teeth have come in. This is a painful process for them, so make sure to have plenty of puppy-safe toys available.
Be proactive- Always reward appropriate behavior when you see it. Redirect mouthy behavior to appropriate items- teach your dog how to play tug, give them long lasting treats and chew items (such as bully sticks, frozen Kong toys, etc.), or a toy to hold in their mouths.
The most common reason for lip smacking in your dog is stress. For some reason, lip smacking is a calming behavior for dogs; and you will often see this behavior when you are scolding the dog or if they are experiencing something that frightens them, like a thunderstorm or loud noise.
Nausea, acid reflux, and a lower quality diet can all be a culprit. All of these cause an increase in the saliva production in the mouth which leads to lip smacking. It is actually a common misconception that dogs such as boxers, great danes and bull mastiffs are supposed to have long ropey drool.
When playtime is over, give her a potty break and then put her up for a rest. When she is loose and attacking your clothes and legs, stop moving and ask her for another behavior that you will reward. If this doesn`t work, calmly put her in her crate with a small treat for a puppy timeout.
Light biting or mouthing is a common way that dogs explore the world around them and is a behavior that dogs will engage in during play. While generally not very enjoyable for us, it is a natural part of how dogs play with each other, and of course how they engage with their toys.
Well, when it comes to the bare basics, it is never too late to train a dog. A dog can learn simple commands such as “Sit”, “Stay” or “Run” no matter how long they are as long as the owner is patient. However, for complex commands and things that go against their instincts.
6 Months Old

Puppies are entering the adolescence stage by this point, and it is the most difficult stage to start training at. That is why it is important to start training them as young as possible!

The behavior is being reinforced.

As puppies, biting was a way for them to try to instigate play and attention, explore the world, and burn off some teething frustration. Which of those three still serves a functional purpose in an older dog? Instigating play and attention.

Sign of Affection!

Dogs have an innate need to express love and affection for their owners, which is why they lick their owner`s faces and hands in the hope of being petted. This behaviour is considered normal and has no cause for alarm.

To lift a medium or large dog comfortably, you want to cradle her in your arms – with one arm around the front of the chest and the other around her hind legs, below her tail and above her hocks, mid-thigh. Press the dog`s body against your chest and lift, making sure the entire dog is well-supported so she feels safe.
This means they want to engage with you and most likely play! They are excited and want to engage in some sort of activity like playing with their chew toys, chasing their ball, or even going for a walk.
Signs Your Dog is Experiencing Oral Pain

Drooling. Whimpering. Halitosis (bad breath) Change in behavior or displaying protective behavior.

For dogs under 6 months of age, much hyper and aggressive behavior is simply puppy play. But that doesn`t mean that you should just green light it and allow it to continue. You must teach your puppy boundaries and the earlier you teach them the better.

Q. My 6 month lab is mouthing too much and it even mouths my hands and legs
ANSWER : A. Puppies chew out of boredom, when playing and during teething. As an owner, it is up to you to teach what is appropriate chewing and what is not. Always provide appropriate chew toys for your breed/size of dog. Correct him/her when chewing inappropriately (either the wrong item or too rough). Praise and reward your pup when he/she chews appropriately. If he/she gets too riled up during play, avoid those actions that bring it to that point.

Q. My Chihuahua was jumping and suddenly started whining. Now she won’t put her hind leg down, but doesn’t cry when I mess with it. Will it heal on own?
ANSWER : A. Leg injuries are very common in small dogs, especially if they have jumped from a high place, or even stumbled and landed on the leg wrong. Leg injuries can be caused by anything from minor sprains and strains, to full blown breaks or joint tears and even arthritis or luxating patellas (knee joints that slip in and out). If the leg appears swollen, dislocated or there is visible bone or bleeding, veterinary care should be sought. Providing strict kennel rest and decreased activity for a day or two can help with minor injuries, however if the limping continues for more than a day you should make an appointment with your local veterinarian.

Q. Hello.. My jack russel has started to get a bowed front leg at the ankle and is causing him to limp quiet a lot.. Is there anything that can be done.?
ANSWER : A. It is possible an injury or deformity of the leg is causing the limp and physical changes you are seeing. Sprains, breaks, strains and even nutritional deficiencies may cause the leg to bow and pain/limping to occur. Having a vet take an X-ray and examine the leg is best to determine the cause of the changes and limp as well as the treatment needed. Casting, bed rest, and medications to treat pain may all be needed to help the leg heal. Until you can get to the vet, a regime of strict kennel rest with leashed walks only to go potty outside will help reduce any further injury to the leg and decrease pain.

Q. Hi. My 14 yr old beagle was just diagnosed with bladder cancer.How much time do we have? By giving peroxicam how much follow up will he need.
ANSWER : A. Bladder cancer (typically Transitional cell carcinoma) has a median survival:
no therapy – 4-6 months
with therapy (Piroxicam + Chemotherapy)- 6-12 months
Long term prognosis is grave.

There are no statistics for just Piroxicam that I came across.

It is recommended to do an ultrasound every 6-8 weeks to determine the disease status and thoracic radiographs every 2-3 months to monitor for spread of the disease.

Q. We have a 4 yr old lab-pit mix we raise from 6 weeks.If my husband tries to take hin by the collar and make him go out to pottie he growls.Problem?
ANSWER : A. This is not good behavior. Rather than take him by the collar, call him to come with you. If he’s not good about coming when called, you can work on that. Keeps treats on hand to to entice him out and reward him when he does go potty and he’ll come to look forward to it. Clicker training is another great way to teach a dog all kinds of things, from obedience to tricks.

Have treats on hand that you know he loves, then simply click and treat. He will come to associate the sound with getting a treat. Start putting distance between you so he has to come to you. Call and click and when he comes to you for that treat, treat him and give him lots of praise. Move to hiding somewhere in the house, call and click. When he comes to you reliably inside when you call, click and treat. When this behavior is consistent, move outdoors with a very long leash. Call and click, if he doesn’t respond, give a light tug on the leash. If he takes even a single step toward you, click, treat and lots of praise. Keep doing this until he comes eagerly. Next, try him off-leash in a securely fenced area. Call and click. At this point he should be responding well and coming easily to the call and click. If he does not, go back to the last step he performed reliably and work on that again until he responds well. Eventually, you can start not treating him every time, but still praise him. Gradually lessen the frequency of the treats until he comes just to the click and praise.

Keep training sessions short, ten or fifteen minutes to start, no more than 30 minutes at a time and do it a few times a day. Try not to do it any time he is overly excited so that he can pay attention to you. Always end a training session on a good note, even if it is just getting him to do something he already does well on command. And never, NEVER punish a dog when they come to you, no matter how far they’ve made you chase them, no matter how frustrated and angry you might be. That teaches your dog that coming to you is a bad thing.

Q. 2 month old Bulldog. While playing gets TOO rough:gripping hand REALLY tight/growling/shaking to the point of drawing blood. Aggresive?Normal?HELP!!
ANSWER : A. For the most part, this sounds pretty normal to me. English Bulldogs can be like this. What you can do is teach him bite inhibition. He needs to know that biting gets him nothing. Each and every time he nips, even gently, you immediately yelp like a puppy would, stand up, cross your arms, and ignore your puppy. Once he is ignoring you, go back to calmly playing with him WITH A TOY. Remember to always use a toy when playing with/petting/interacting with puppies. They will be teething very soon, and they don’t understand that biting you is inappropriate, so using a toy to redirect their attention is important. He needs SOMETHING to bite, or else he will choose your hand. Give him more options.

Another thing you can do is have a toy that YOU OWN. This can be a soft braided rope toy or something of the like. Dot not allow your dog to have this toy whenever he wants. This toy disappears when you are done playing with him with it, and reappears when you want to play. Never allow him to “win” games with this toy. Eventually, the toy will hold so much meaning, when he sees it, he will be instantly interested in the toy instead of your hands.

It also helps to have two bags of toys. Bag#1 is full of chew toys/rope toys/soft toys/etc. It comes out for one week, and then disappears and out comes Bag#2. Bag#2 has the same types of toys in it. This will keep the toys feeling like “new” to your pup and make him less likely to chew on you during play!

Q. My sister’s dog is digging the hair off from his legs. Any advice?
ANSWER : A. Biting and chewing to the point of hair loss can be caused by a number of things. Allergies, skin infections, and even metabolic illnesses can all cause the skin to become bothersome, or hair to be lost. In some cases, the behavior of licking or chewing at the hair can become chronic, and lead to infections or sores on the leg.

It is best to have your sister bring her dog in to have the legs looked at. Your vet can check for any signs of infection, allergy or even external parasites and provide treatment for relief. If there is no apparent cause, your vet may also recommend a blood test to check for internal illness as the cause.

Until you can get to the vet, it is best to prevent the dog from licking or scratching at the area. An Elizabethan collar (cone) is best to stop the behavior and allow the legs to rest some until they can be examined. If there is any dirt or debris in the area, a warm clean washcloth can be used to keep the area clean and prevent secondary infection until it can be examined.

Q. I have a 9 week Chihuahua and a 5 yr old Lab mix as well as two cats and we are having a flea plage in my house. How do I get rid of them quickly?
ANSWER : A. You need to use a good flea product like advocate or stronghold. Every four weeks for at least 6 months and house spray like indorex or rip. Because there is nothing that kill fleas in the pupi stage it can take 6 months of continued treatment to get rid of them all as they need to hatch before they will die.
