How to Identify Common Pet Problems ?

The most typical cause of facial swelling in dogs is an allergic reaction. Bug bites, bee stings, vaccinations, medications, certain foods, toxin exposure, and pollen are just some of the many potential allergens that could be affecting your dog if they are presenting a swollen face.
Trauma – Trauma, such as a bite wound or injury, can cause lymphadenopathy in the affected area. Medications – Certain medications, including antibiotics and anticonvulsants, can cause lymph node enlargement in dogs.
Traumatic events can sometimes cause facial swelling, but when the trauma site gets infected, your dog`s head and neck can get lopsided swelling. Often, after an animal bite or penetrating injury, abscesses on the head and neck will appear suddenly. There is also usually a fever associated with the swelling.
Dogs have several salivary glands located in the neck and area around the jaw. Swelling of the salivary glands (sialocele) occurs when one (or more) of these glands leaks saliva into the tissue surrounding the gland.
Facial paralysis is quite common in dogs, particularly in middle to old-age. The term is simply the description of drooping of muscles in the face, which is caused, not by damage to the muscles themselves, but to the nerves supplying them.
Pain and swelling may be reduced by pain medication and steroids. If the swelling in your dog`s mouth is the result of an underlying condition, your veterinarian will work on treating that condition so that your dog`s signs (including inflammation of his mouth) will be resolved.
Enlarged lymph nodes

Common places to find an enlarged lymph node include lumps on your dog`s neck under their jaw or a lump in their armpit. Enlarged lymph nodes can mean anything from your dog fighting a small infection to canine lymphoma developing in that area.

Glands can also swell following an injury, such as a cut or bite, near the gland or when a tumour or infection occurs in the mouth, head, or neck. Glands in the armpit (axillary lymph nodes) may swell from an injury or infection to the arm or hand.
Mild swelling may resolve on its own, but you still need a vet to check your pet out and determine why their face swelled up. If the cause is due to dental disease, treatments can range from cleaning to tooth removal.
A salivary mucocele, also known as a sialocele, is an accumulation of saliva that has leaked from an injured salivary gland or salivary duct. This leaked saliva accumulates within the tissues of the mouth and neck, resulting in a soft, painless swelling.
Facial swelling in dogs can be life-threatening if the swelling progresses to the throat, so don`t try to diagnose the cause of your dog`s swelling yourself. If your pet`s face looks swollen, or lopsided, get your dog to a veterinarian immediately.
Lymphoma affects the lymph nodes and causes them to swell up to the size of golf balls. In case you don`t know, dogs have lymph nodes all over their bodies. Lymph nodes are found under the chin, at the back of the leg, near the leg joint, and around the shoulder.
Dogs will lick their lips non-stop as an appeasement gesture when feeling threatened, anxious, or nervous, or when they experience a health-related problem such as nausea, oral discomfort, allergies, or internal pain.
This is just a natural consequence of genetics. The saggy skin around a dog`s lower muzzle and throat even has a name: It is referred to as a “dewlap,” and it can range from only mildly noticeable to extremely obvious and pronounced depending on the breed of dog.
Unfortunately, there aren`t any home remedies for facial swelling in dogs. This is because the most likely causes of facial swelling are allergic response, infection, or injury, all of which require veterinary attention. Facial swelling of any kind should be assessed by a veterinarian immediately.
While you need a veterinarian to verify, many lumps aren`t cancerous. Sometimes dogs can develop fatty tumors called lipomas. Lipomas consist of fat cells that accumulate in one place. While they don`t threaten your dog`s health, we can surgically remove them to reduce irritation.
A lipoma is a term to describe a very common benign tumor of fat seen in middle-aged to older animals. These tumors can vary in terms of their rate of growth (some may remain the same size for years) but become problematic for your pet when they grow in locations that impact their ability to walk or cause discomfort.
It can be an allergic reaction, dental issue, trauma, or a growing tumor. Most commonly, acute (sudden) facial swelling in dogs occurs as a result of an allergic reaction. Facial swelling that develops more slowly may be in the result of a facial growth or tumor.
While there is no known cure for lymphedema, there are ways to treat and manage its symptoms. Lymphatic drainage massage is one of the most popular methods to relieve the pain and swelling caused by swollen lymph nodes.
Typically, lymph nodes stay swollen for about 2 weeks or so. However, physicians may become concerned if your lymph node stays swollen for more than 4 weeks . Even if they remain swollen for that many weeks or longer, it`s rare that your swollen lymph node would indicate cancer.
Severe instability can lead to extreme pain and paralysis from pressure on the spinal cord. Some dogs can recover with strict cage rest and a chin to chest neck brace; other dogs require surgery to stabilize the neck and decrease the pressure on the spinal cord.
What are the typical signs of pain in dogs? General behaviour: Shaking, flattened ears, low posture, aggression, grumpy temperament, panting or crying, excessive licking or scratching a specific area, reluctant to play, interact or exercise, lameness (limping), stiffness after rest, loss of appetite.
Swelling and Redness of the Joints

In cases of moderate to severe sprained legs in dogs, a dog`s injured leg could become very swollen. Although swelling may not occur with mild sprains, it can be a useful indication of some type of leg injury otherwise.

If you can see obvious bite wounds, you should seek immediate veterinary attention. Wounds that appear to be minor on the surface can be deceptive and may have the potential to be life-threatening, depending on the location of the injury.

the most relevant questions and answers related to your specific issue

Q. How do I determine how much my overweight pet should weigh?
ANSWER : A. There are many tools to determine overweight and obesity levels in pets. A new tool, morphometric measurements and body fat index, are available to accurately determine a pet’s ideal weight; this will allow an accurate determination of the amount of food a pet should receive to achieve weight loss. Feeding the correct amount will lead to greater weight loss success.

There are many weight loss food options to help pets reach their ideal weight. Your veterinarian can help make a ideal weight recommendation. Here are some tips to help your dog lose weight in a healthy and safe way:

1. Diet: Providing a healthy and well balanced diet is essential to your pet’s overall health. Finding the right food for your dog can be a challenging process. For those overweight animals many commercial dog companies offer weight loss diets, but it is important to evaluate food labels for adequate nutritional content.

You want to ensure you are not missing other essential vitamin or mineral content. Volume of food is also important and the amount of food that works for one breed of dog may not be the same for another breed of dog. Portion control as opposed to free-choice feeding can help your dog to drop a few unnecessary pounds.

There are also prescription weight loss foods designed by veterinary nutritionists, such as Hill’s r/d (http://bit.ly/1AoENSd). Some pet owners find that home cooking is the best option for helping to provide a well-balanced and realistic diet plan. There are websites such as balanceit.com that offers recipes to fit your dog’s specific needs. Consulting with your veterinarian or a veterinary nutritionist to find the appropriate diet is a great way to help your dog be as healthy as possible.

2. Exercise: Another great tactic for weight loss for your dog is exercise. Whether this is through running, walking or playing with a favorite toy all of these are wonderful types of exercise to help keep your dog at a lean and healthy weight.

For those pet owners with busy schedules utilizing professional dog walking services or playtime through dog daycare services is another option. It has been shown that those pet owners that exercise regularly with their pets generally live a healthier lifestyle.

3. Physical therapy: As animals age pet owners offer encounter their favorite canine having more difficulty walking and have a dwindling desire to play with toys. Physical therapy, specifically hydrotherapy is a wonderful way to help older and arthritic animals gain more mobility and lose weight. Hydrotherapy has been proven to have several therapeutic effects on the body including, muscle strengthening, relief of swelling, decreased joint pain, less stiffness in limbs, improved circulation, weight loss, and increased tissue healing to name a few. For more information on the benefits of hydrotherapy:

4. Veterinary visit and blood work: Weight gain can also be related to underlying health concerns such as hypothyroidism or other endocrine disorders. Scheduling a veterinary evaluation and routine blood work can be another important component in increasing the longevity of your dog’s life. Conditions such as hypothyroidism that predispose dogs to gain weight can be treated with a daily medication to improve hormonal balance. If feel that your dog is unnecessarily overweight there can be an underlying health condition that needs to be addressed.

5. Healthy treats: Pet owners love the chance to reward their favorite canine companion with treats and most dogs jump at the chance to consume these delicious products. The problem is many treats, which can include commercial dog treats or table scrapes can add many unnecessary calories to your dog’s daily intake. Reading labels and making note of the calories in these treats is an important component of understanding your dog’s overall health. Treats should not exceed more than 10 percent of your pet’s daily calories. There are healthier treats that can be offered to your pet to keep calories lower yet provide a fuller sensation. A pet owner can add steamed or pureed vegetables, such as carrots, green beans or sweet potato to add more fiber and thus a fuller feeling for your dog.

Q. My Bulldog puppy growls, barks and even tries to bite me when I say “no” to him. What can I do?
ANSWER : A. First, avoid scolding him and acting aggressively towards him if you don’t want him to be acting aggressively towards you. There are other methods you can use to communicate to your dog that you don’t want him to continue doing what he is doing. I recommend you stop telling him “no”, scolding him, or raising your voice at him. Everything coming from you should be 100% positive and 100% calm.

Try to figure out ways to clearly communicate what you want to your dog. If you want your dog to leave something or someone alone, I strongly suggest teaching your dog commands like “leave it”. Here is a link to a video in which I explain how to do it:

www.youtube.com/watch?v=R1TS5nA7z5Q

Another thing I suggest you use is a no-reward marker. This clearly communicates when your dog has done something wrong. No-reward markers have to be introduced during your training sessions. You should be doing at least three training sessions per day, that are something like 3-10 minutes long (working on different things each training session). If you are teaching your dog something BRAND NEW, do not use the no-reward marker, as you do not want to discourage your dog from performing behaviors for you. Use the no-reward marker for known behaviors only. Here is another helpful video about this:

www.youtube.com/watch?v=sdU5a6fXKlg

Lure each new behavior (as shown in the video) using high value treats. Let’s say you’re working on “down” which is a behavior your dog knows fairly well. Present the treat to your dog. Ask your dog to “down” (only ask once). If he does not go “down” immediately, say, “uh-oh” or “eh-eh” in a gentle tone, and then place the treat behind your back. This communicates to your dog that they did something to make the treat go away.

After you place the treat behind your back to show your pup “that was wrong” you need to communicate to your pup “let’s try again” by getting your pup to walk around for a second, and then start the behavior all over again. If your puppy is very young, chances are you haven’t taught him a solid “down” behavior yet. So, as I said, do not use this method until you have lured each new behavior as shown in the video.

This is the order in which you should teach behaviors: Lure using a high value treat as shown in the video. After a few successful food lures, lure with an empty hand. If the pup is successful with the empty hand lure, reward with lots of treats. If the pup is unsuccessful, then go back to food-luring a couple more times. After a few successful empty-hand lures, you can begin to add the cue. Say “sit”, then lure with an empty hand, and then reward. Once your pup understands the cue, begin to work on the no-reward marker.

Q. Whenever I take my dog on walks he always barks at people and others dogs in my neighborhood. What should I do to resolve the problem
ANSWER : A. The very first thing to do is to make sure your dog is getting sufficient physical and mental exercise every day. A tired dog is a good, happy dog and one who is less likely to bark from boredom or frustration. Depending on his breed, age, and health, your dog may require several long walks as well as a good game of chasing the ball and playing with some interactive toys.

Figure out what he gets out of barking and remove it. Don’t give your dog the opportunity to continue the barking behavior.

Ignore your dog’s barking for as long as it takes him to stop. That means don’t give him attention at all while he’s barking. Your attention only rewards him for being noisy. Don’t talk to, don’t touch, or even look at him. When he finally quiets, even to take a breath, reward him with a treat. To be successful with this method, you must wait as long as it takes for him to stop barking. Yelling at him is the equivalent of barking with him.

Get your dog accustomed to whatever causes him to bark. Start with whatever makes him bark at a distance. It must be far enough away that he doesn’t bark when he sees it. Feed him lots of good treats. Move the stimulus a little closer (perhaps as little as a few inches or a few feet to start) and feed treats. If the stimulus moves out of sight, stop giving your dog treats. You want your dog to learn that the appearance of the stimulus leads to good things.

Teach your dog the ‘quiet’ command. Oddly, the first step is to teach your dog to bark on command. Give your dog the command to “speak,” wait for him to bark two or three times, and then stick a tasty treat in front of his nose. When he stops barking to sniff the treat, praise him and give him the treat. Repeat until he starts barking as soon as you say “speak.” Once your dog can reliably bark on command, teach him the “quiet” command. In a calm environment with no distractions, tell him to “speak.” When he starts barking, say “quiet” and stick a treat in front of his nose. Praise him for being quiet and give him the treat.

As in all training, always end training on a good note, even if it is just for obeying something very simple, like the ‘sit’ command. If you dog regresses in training, go back to the last thing he did successfully and reinforce that before moving on again. Keep sessions short, 15-20 minutes max, and do this several times a day.

Q. Rescued a dog almost two weeks ago, and now that her kennel cough is gone her personality shines!! No previous training, how should I start?
ANSWER : A. POST FOUR:

After your dog is familiar with the behavior you lured from scratch, and taught to your dog, you can start to use the “no-reward marker” I talked about. What you do is ask the dog to perform the behavior, and if the dog does not perform the behavior, you simply say your no-reward marker (choose one: eh-eh, hey, uh-oh, oops) show them the treat, put it behind your back, and BRIEFLY ignore your dog. Just turn your back for a second or two, before turning back to your dog and saying, “let’s try that again.” When you’re ready to start over with your dog, make sure you move around. If you are repeating the same cue while in the same position, while your dog is in the same position, you are likely to receive the same results. The more you move around, and start fresh, the better your chances are of having your dog listen to your cue the second time around. BIG rewards when they dog it successfully! Lots of praise and treats.

My no-reward marker is “hey.” When my dog does something wrong I say, “hey” and she immediately understands that she needs to offer a different behavior. This is clear to her. I don’t have to say it in a mean way, I simply say, “hey” in a normal tone of voice and she understands what the word means.

Once you’ve built up that connection and communication with your new dog, you can work on all kinds of fun behaviors! I personally enjoy the more zen-like behaviors: https://www.youtube.com/watch?v=ruy9UMcuGh8

I like to teach my dog fun tricks that offer her a “job” to do of sorts like object retrieval: https://www.youtube.com/watch?v=I4iertZSva8

(object retrieval training completed; what it looks like: https://www.youtube.com/watch?v=jx0Dml28FGY)

Scent-games are fun too! Very confidence building. Hide a REALLY smelly treat in a box, and place that box in a line of boxes. Let your dog go in the room while saying something like “search!” or “find it!” and watch them hunt for that smelly treat! Lots of rewards when they find it!

Q. I think my dog was bitten by something, under chin and neck is swollen. Lower lip is hanging down due to swelling. No pain seems present.
ANSWER : A. Could allergic reaction to something. Should get better if not exposed anymore. The thing to keep an eye on is as swelling is on face it could affect her airways. This is then life threatening. So if getting worse or showing any other symptoms then would bebest to see vet ffor ttreatment.

Q. I think my dog was bitten by something, under chin and neck is swollen. Lower lip is hanging down due to swelling. No pain seems present.
ANSWER : A. I would recommend having it checked as soon as possible due to the location of the swelling in case it starts affecting the breathing.

Q. My dog keep hacking like a cough or something in her throat, what can I do?
ANSWER : A. Hacking and coughing can be caused by a number of things ranging from foreign bodies such as twigs stuck in the mouth or throat, to infections or illnesses such as Bordetella or Kennel cough, common in dogs that frequent kennels, dog daycare or dog parks. In older dogs, heart and lung issues can also be indicated by a cough that does not go away.

If you think there may be a foreign object stuck in your dog’s throat, you can sweep a finger gently through the back of the mouth or throat if your dog will let you. If something feels stuck and is not easily moved by the finger, it is best to contact your vet to have the object safely removed. This usually requires sedation so that your dog does not become panicked or move, causing the object to become further stuck or cut the throat.

If your dog is showing other symptoms of illness in addition to the cough such as runny nose or eyes, fever, lethargy or changes in appetite, it may indicate a viral or bacterial illness such as kennel cough. These are usually treated with a cough medication in severe cases, plus rest and treatment of any additional symptoms until the condition improves. In bacterial causes, antibiotics may also be given to help your dog feel better.

If your dog has a constant cough that does not go away, or has had changes in ability to exercise, breathing, or appears to have swelling around the chest or abdomen, in may indicate a lung or heart issue. Your vet can thoroughly examine your dog for any signs of heart or lung problems and can then offer care as needed depending on the cause.

Q. Shiba Inu. He periodically shakes and trembles, usually unrpovoked and seeming for no reason. Usually cuddling helps but not always. Becomes reclusive
ANSWER : A. I do find that Shiba Inu’s are a really sensitive breed. I think the first thing to rule out is pain. That could be pain from a muscle injury or even gastrointestinal pain. Try to pinpoint whether it occurs after a meal or not. He might be painful due to something going on in his GI tract, and the pain is at its worse after he eats.

I’ve also seen a lot of small breeds like Shibas get back pain, and shaking can definitely accompany that as well. If you haven’t see your vet who can perform a good physical exam and look for any signs of muscular pain along the spine or elsewhere. It’s not a bad idea at this point to consider doing some blood work just to screen for any problems that could be affecting organ function, for example.

If he’s healthy otherwise, I think it’s likely that there’s something that’s scaring him at home. These things can be really difficult to identify, and you have to be really aware and note exactly when the shaking occurs, how long it lasts, etc, and look for patterns. Dogs can hear things we can’t, and he may be hearing things you’re missing, and the noise is disturbing to him. Cuddling is a good idea, also working to distract him and desensitize him with toys and treats might help. But like I said above – definitely rule out pain first.
