How to Identify Common Pet Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced pet care professionals :

Toy breeds (such as Yorkies, Poodles, and Dachshunds) are very susceptible to dental disease, and often have enlarged submandibular lymph nodes when they have infected teeth and gums.
There are many good dental products on the market. But brushing your dog`s teeth is still the best way to ward off dental disease. This is important because, as we discussed, bad teeth in dogs can cause swollen lymph nodes.
One of the most common causes of swollen lymph nodes in dogs is due to an infection within the body. Infections may be within the lymph node itself or be a reactive lymph node (reactive lymphadenopathy) from a distant source.
Immune-mediated diseases – Autoimmune diseases such as lupus, immune-mediated hemolytic anemia (IMHA), and polyarthritis can cause lymphadenopathy. Cancer – Cancerous tumors can cause lymphadenopathy in dogs. Lymphoma, a cancer of the lymphatic system, is a common cause of swollen lymph nodes in dogs.
Bacterial and Fungal Infections

Typically, the lymph nodes in dog`s throats become most swollen during this type of bacterial infection. Dogs have comparable Strep throat symptoms to human infections including difficulty swallowing, coughing, fever, pain and lethargy.

Tooth Abscess

Cavities, dental work, or a mouth injury can lead to an infection in your tooth. This can cause swelling in the lymph nodes under your jaw or in your neck.

Clindamycin is a prescription antibiotic used in the treatment of serious infections such as soft tissue infections, dental infections, and bone infections. Give this medication the entire length of time prescribed by your veterinarian. Symptoms may get better before the infection is fully treated.
Some breeds predisposed to lymphoma include: Chow Chow. Basset Hound. Scottish, Airedale, West Highland White, Yorkshire, and Bull Terriers.
Lymphoma of the skin is commonly mistaken for allergies or fungal infections at first; when it occurs in the mouth, it may be misdiagnosed as periodontal disease or gingivitis. When lymphoma in dogs occurs in the gastrointestinal system, vomiting and unusually dark-colored diarrhea are the primary symptoms.
Typically, swollen lymph nodes caused by infection are treated with vet-prescribed antibiotics or antiparasitic or antifungal medication. Lymphoma is usually treated with chemotherapy, she adds.
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.
Swollen lymph nodes in different places around the body can be a sign of serious systemic infection, but potentially also of a common type of cancer. The emergency vet may not be able to diagnose your dog overnight, but may well find a way to make her more comfortable than she is at present.
Toxoplasmosis is seldom diagnosed or reported because most patients with a healthy immune system have no signs or symptoms of the disease. Some short-term effects of toxoplasmosis may include fever, muscle pain, sore throat, headache, swollen lymph nodes and fatigue.
Any allergen—such as pollen, dust mites, mold, or animal dander—is a foreign substance in the body and therefore triggers an immune response. This allergic response can in turn trigger the lymphatic system and lead to swollen lymph nodes.
Seasonal allergies, pet allergies, and dust allergies can cause runny nose, congestion, and sneezing, just like infections. That said, these allergies don`t cause swollen lymph nodes or fever, but infections can cause those symptoms. Food allergies also do not cause swollen lymph nodes.
The glands on either side of the neck, under the jaw, or behind the ears commonly swell when you have a cold or sore throat. Glands can also swell following an injury, such as a cut or bite, near the gland or when a tumor or infection occurs in the mouth, head, or neck.
When more than one area of lymph nodes is swollen it`s called generalized lymphadenopathy. Some infections (such as strep throat and chicken pox), certain medicines, immune system diseases, and cancers like lymphoma and leukemia can cause this kind of swelling.
One of the best treatments for swollen gum issues is a dental cleaning. A professional can clean deep inside the gums to remove excess bacteria build-up. With less bacteria to fight, swollen lymph nodes will go down.
Treatment for abscessed teeth in dogs includes antibiotics, pain medication, and extraction of the affected tooth. Antibiotics are often started 3 days before the dental surgery and tooth extraction. They are also used to help prevent infection from spreading to other parts of the body.
Using a warm salt water rinse or an oral gel specifically for dogs. If your dog`s gums are already inflamed, you can use a warm salt water rinse or an oral gel specifically for dogs. A warm salt water rinse can help reduce swelling and inflammation of the gums and remove bacteria from the mouth.
Some combination antibiotics contain amoxicillin and clavulanic acid, which is highly effective at treating gum disease and certain skin infections. Your vet may prescribe amoxicillin in addition to other antibiotics for infections in which the bacterium is unknown or unidentified.
What causes lymphoma in dogs? Unfortunately, the cause of lymphoma in dogs is not known. Although several possible causes such as viruses, bacteria, chemical exposure, and physical factors such as strong magnetic fields have been investigated, the cause of this cancer remains obscure.
Dogs with lymphoma tend to feel fine at first, so you may not notice any other signs of illness. An exception is that if your dog`s blood calcium levels rise, he may lose his appetite, act lethargic, and possibly drink more water due to potential kidney damage.
Final Stage Dog Lymphoma Symptoms

Breathing difficulties (which is frequently indicated by laboured panting) Glassy eyes. Restlessness and discomfort. Unwillingness or inability to move or even stand.

Q. How can I remove internal ticks?
ANSWER : A. If you mean the ticks are embedded deeply in the skin, you can use a pair of tweezers to gently remove the tick. If the head becomes detached, most healthy bodies will push the head out of the skin naturally over a period of time. Using Vaseline over the tick can also sometimes cause it to back out on its own and be removed. Getting your dog on a monthly flea and tick preventative can help prevent future ticks from hopping on, also, if you are in an area where tick-borne disease are a problem it is always a good idea to have any tick bites examined by your local veterinarian.

If you mean the ticks were eaten, they will most likely pass through your dog without problem. However if you suspect there is an issue, your vet should take a look.

Q. Which flea and tick drops are the best and why?
ANSWER : A. Your question is a good one, and unfortunately the answers are going to differ based on who you ask. Many vets are seeing resistance to Frontline, which has been the go-to product for many of us for many years. It contains the active ingredient Fipronil, which is very safe and typically extremely effective. I use it on my dogs and never see fleas or ticks. However other vets will tell you in their areas, for whatever reason, they are seeing fleas and ticks on dogs and cats on which this product was used.

Another reason opinions differ is that some people like to give an oral product, and some like to put a topical product directly on the skin. That’s a matter of personal preference mostly. Bravecto, as mentioned below, is one of those products. Most people find it safe and effective. It uses a different process that Frontline to kill fleas and ticks.

In general the products you buy over-the-counter are likely going to be less expensive and less effective than what you get from a vet. I think the reason is that the more expensive products contain newer insecticides, and likely less resistance to these products has built up in the flea and tick population but also they are maybe less “proven”, so it’s important for a vet to be involved in the use of the product in order to ensure that there won’t be a negative reaction to using it.

If I lived in an area where there was Lyme disease (in the US that’s the northeast and upper midwest) I’d most definitely add a tick collar to my standard oral or topical flea and tick prevention. AND I’d search both of my dogs everyday for ticks. It’s because nothing you buy will be 100% effective, and Lyme disease can be a very serious problem.

If you want to talk further and talk more specifically about where you live and what products you’re considering, I’d be happy to do a consult with you. Nobody here is paid to recommend products, but we do develop preferences based on what we use on our own pets and in our practices.

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. My dog had very red gums. He is also eating grass. Is this normal?
ANSWER : A. Normal gums on a dog are usually a pinkish color, and can be checked for health by lightly pressing down on the gum until it turns white. When your finger is removed, the color should return within 2-3 seconds. In dogs that are anemic or ill, the gums will continue to be a pale white color for a long period. Gums that are blood red, or appear to be bleeding can indicate a problem such as a bleeding or blood clotting disorder, and can also sometimes indicate ingestion of a poison or toxin causing a bleeding disorder.

If your dog’s gums are actively bleeding or blood red, you think your dog may have ingested something toxic or poisonous, or he has other symptoms of bleeding, lethargy, or illness, it is best to contact your local veterinarian or emergency clinic immediately for treatment.

Q. I was told by my vet that my dogs cherry eye was caused by something hitting his eye when he was poking around under a bush. I was told surgery needed
ANSWER : A. Prolapsed gland of the eyelid refers to a pink mass protruding from the animal’s eyelid; it is also called a “cherry eye.” Normally, the gland is anchored by an attachment made up of fibrous material. The most common sign of “cherry eye” is an oval mass protruding from the dogs’s third eyelid. It can occur in one or both eyes, and may be accompanied by swelling and irritation. He may have acquired it by getting an injury to his eye but this isn’t the case sometimes. Sometimes there is a weakness in the fibrous attachment.

The veterinarian will review the mass in the dog’s third eyelid and determine if there is an underlying cause for the condition. The diagnosis of the prolapsed gland could be scrolled or everted cartilage in the third eyelid, abnormal cells in the third eye, or a prolapse of fat in the dog’s eye.

Treatment often includes surgical replacement of the gland in the dog’s eye, or removal of the entire gland if the condition is severe. Conversely, if medications are recommended, they are typically topical anti-inflammatory drugs that are effective in reducing swelling.

Q. Why does my dog keep licking her butt alot? We can’t take her to the vet. But, after the bath, she seem fine and not lick her butt alot.
ANSWER : A. I would ask the vet (or groomer who gives the bath) if they are expressing your dog’s anal glands during the bath. This is a very common thing for them to do and it would explain why your dog is so comfortable after a bath. It would also explain why your dog licks her bum so often! Dog’s have these bothersome glands that are located right next to their anus called anal glands. These glands fill up every week or two with fluid (in some cases, very thick fluid) and many dogs have a hard time expressing this fluid on their own. This causes them a great deal of discomfort and in turn causes them to lick their bum! Some dogs will even scoot their bum on the carpet in an effort to empty the glands. Your vet (or your groomer in this case) can help you and your dog out by emptying these glands out on a regular basis and keeping your dog comfortable.

Q. My dog appears to have a bite possibly from a tick on her skin, it is red and lumpy but I cannot see a tick. What do you recommend
ANSWER : A. A tick’s bite can be very irritating and frequently results in a ‘granuloma’ after the tick completes feeding and drops off. These granulomas typically resolve in a week or two. Monitor for redness or discharge. Keep the site clean and dry. Prevent licking or scratching if possible. Use a monthly tick preventative such as Frontline Plus, K9 Advantix or Vectra to prevent tick bites.
