How to Identify Common Pet Problems ?

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

Acute inflammation of the testis and/or epididymis is most commonly infectious (bacterial, fungal or viral). The source of infection can be hematogenous or urologic or by direct inoculation. Clinical signs include pain and enlargement of the testis or epididymis.
If your dog is coughing and sneezing, he could very well be suffering from canine influenza, also known as `dog flu. ` Canine influenza is a relatively new disease, similar to the equine (horse) flu virus, to which dogs have no natural immunity.
Kennel cough is usually illustrated by inflammation of the trachea, but it can also lead to bronchopneumonia.”
Scrotal swelling or pain could be caused by many things, including: an injury. an infection such as mumps and other causes. Epididymitis is one of the most common causes of scrotal pain in men.
The exact cause of a reverse sneeze is unknown. Any irritation to the nose, sinuses, or back of the throat can trigger an episode of reverse sneezing. Irritants include nasal mites, secretions, foreign bodies such as seeds, pollens, grasses, allergies, smoke, odors, masses, or an elongated soft palate.
Other things that could be causing your dog to sneeze include allergies to airborne allergens or certain foods, nasal infections and nasal mites. Excessive sneezing can also be a sign of something serious like a tumour but this is more rare. Sometimes dogs sneeze as a sign of excitement or playfulness.
Kennel Cough is the common name for a group of diseases similar to the human cold or flu. Symptoms are fever, swollen tonsils or lymph nodes and a deep, “honking,” keep-you-and-the-dog-up-all-night cough that takes weeks to go away.
Signs of heartworm disease may include a mild persistent cough, reluctance to exercise, fatigue after moderate activity, decreased appetite, and weight loss. As heartworm disease progresses, pets may develop heart failure and the appearance of a swollen belly due to excess fluid in the abdomen.
Encourage Your Dog to Rest

Adequate rest is one of the best remedies for kennel cough. If your dog gets plenty of sleep, it will give his body a chance to fight the virus and recover properly. Put your dog in a room by himself, away from kids and other pets. This way, he will not be disturbed while trying to rest.

An epididymitis infection can lead to serious problems if it`s not treated in a timely manner. Chronic epididymitis could cause an abscess to form on your scrotum. Or it could destroy your epididymis, resulting in infertility. In some cases, the infection can spread to other parts of your body.
What is a hydrocele? A hydrocele is produced by fluid in the sac which normally surrounds the testicle. It often presents as painless swelling in the scrotum (the pouch that holds the testicle). Hydroceles are often found in newborn boys, especially premature infants.
A sudden and severely painful swelling in one of your testicles can be a sign of a condition called testicular torsion, which is where the blood supply to a testicle is interrupted. In rare cases, testicular lumps can be a sign of testicular cancer.
Orchitis (or-KIE-tis) is an inflammation of one or both testicles. Bacterial or viral infections can cause orchitis, or the cause can be unknown. Orchitis is most often the result of a bacterial infection, such as a sexually transmitted infection (STI). In some cases, the mumps virus can cause orchitis.
You should start to feel better within a few days, but it may take up to 2 weeks to fully recover. It`s important to finish the whole course of antibiotics, even if you start to feel better. There are some things you can do while you recover to help ease pain and swelling and prevent any further problems.
It takes about 6 to 8 weeks for the swelling to go away. You may have to have many follow-up visits with your urologist to chart your progress. If conservative measures (meds and jock strap) don`t work, surgery may be needed and the testicle may have to be removed.
Some of the most common reasons why your dog is coughing are heart disease, pneumonia, kennel cough, tracheal collapse, heartworm disease and canine influenza. Keep track of any other symptoms, such as coughing blood, mucus, foam, etc.
Common clinical signs include a loud cough, often described as a `goose honk`, runny eyes and nose, swollen tonsils, wheezing, lack of appetite, and depressed behavior. Most dogs with infectious tracheobronchitis will cough when the throat is rubbed or palpated or during and after exercise.
Sneezing and Reverse Sneezing

Reverse sneezing may also occur in dogs with kennel cough, although it isn`t quite as common as regular sneezing. Reverse sneezing also sounds like honking, much like the cough associated with kennel cough.

If your dog sneezes a few times and has no other signs of illness or discomfort, then it`s unlikely to be something to worry about. If your dog shows any of the following signs, then you should speak to your vet for advice immediately: Excessive, persistent, frequent or uncontrollable sneezing.
As pet owners,if you notice your dog sneezing, it`s normal, it`s important to emphasize that this can be completely normal. However, if your dog starts sneezing more often, or has a sudden, severe episode of sneezing that doesn`t resolve, it could be a sign that they need to see a veterinarian.
What are signs of canine influenza in dogs? The signs of this illness in dogs are cough, runny nose, fever, lethargy, eye discharge, and reduced appetite, but not all dogs will show signs of illness.
Infectious causes of swollen lymph nodes in dogs

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.

Swabs can be taken to determine the exact virus or bacteria causing kennel cough – although this isn`t always useful for treatment. If there are suspected complications, radiographs can be used to assess a dog`s condition.
The first few days are the worst. The cough will often be triggered by things like barking, pulling on the lead, getting excited or going out in cold air. Symptoms generally resolve over about 7–10 days. To prevent spread, try to keep your dog isolated from other dogs while he has active symptoms.

the most relevant questions and answers related to your specific issue

Q. My new puppy is coughing a lot and I think it is Kennel Cough. Could it be?
ANSWER : A. Kennel Cough is similar to the human cold, and it can be caused by three categories of microorganisms.

1. Bordetella Bronchiseptica: A small bacteria which can result in bronchitis and severe cough in dogs.
2. Canine Adenovirus: A serious and contagious virus.
3. Canine Influenza Virus: An extremely contagious virus causing mild to severe respiratory symptoms in dogs.
Kennel Cough has its own course of 1 to 3 weeks and can be managed medically.

Close environments with several dogs can increase the chance of dogs catching the cough. Kennel Cough vaccination is aimed mostly at preventing the Bordetella infection through an inhalant or injection vaccination. Although not 100% effective, it should be recommended in all dogs that spend time around other dogs, even the park is considered one of these social occasions.

Kennels have their own policy with regards to Kennel Cough vaccinations and should always be contacted well ahead to understand and comply with their requirements before the stay of your dog.
If you suspect that your dog has caught Kennel Cough, you should see your veterinarian. Your dog might benefit from certain medications to speed up his recovery. These might include antibiotics, anti-inflammatory drugs, and cough suppressants at your vet’s discretion.

Q. My C. K. Charles has an asmathic cough. Ok most of the day, but worse in hotter rooms in the evening. What’s wrong?
ANSWER : A. Coughing in dogs can be caused by a number of things including allergies, asthma, illness such as Bordetella (kennel cough) or even lung and heart problems.

Allergies and asthma can cause a dog to have a raspy cough, and they may wheeze, sneeze or have running noses or trouble breathing when active or in an area where the allergen is present. Your vet can determine if an allergy or asthma is present and provide medication as needed to help with symptoms.

Bordetella can also cause a deep hacking cough, and is common in dogs that frequent doggy day cares, kennels or dog parks. The causes can be bacterial or viral, and treatment depends on if any secondary symptoms such as fever or dehydration is present. Treatment involves cough suppressants from your vet, or even antibiotics and fluids to treat secondary illnesses. Other illnesses such as heartworm may cause a chronic cough and exercise intolerance and should be looked for if your dog is not already on a heartworm preventive.

Small dogs are also prone to a condition called collapsing tracheas, and Cavaliers are very prone as a breed to heart and lung issues. Collapsing tracheae often cause a gasping or hacking cough when excited or active, and may require treatment if they become problematic. Heart and lung problems such as heart failure or genetic abnormalities can also cause coughing as a sign of the illness. Your vet can perform a complete exam to check the health of the lungs and heart.

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. We brought 2 new kittens home. One of them is sneezing. We have a Sr cat and an adult who is now coughing. What to do?
ANSWER : A. Commonly respiratory infections (viral -Herpesvirus and Calicivirus- and possibly bacterial) can cause sneezing episodes in kitten especially if not vaccinated yet. If your kitten is affected by respiratory infection could develop or have more signs such as discharge from eyes, more discharge from nose, coughing, being lethargic, depressed and inappetent.

The coughing episodes of the adult cat could be completely unrelated to the cause of sneezing of your new kitten, especially if your adult cat is already vaccinated.

The cause of cough in adult cats are not necessarily related to respiratory problems, heart problems could cause that as well.

Keep the nose and the eyes of your kitten free from discharge, keep your kitten warm and take both of them to your veterinarian as soon as possible to identify the cause and the relationship of the two problems and treat appropriately.

Q. Dog-persistent loud frequent cough 30+days; still has good appetite,doesn’t act sick. Need names of effective cough suppressant & anti-inflammatory
ANSWER : A. I would not recommend use of any cough suppressant until you have an accurate diagnosis as to why your dog is coughing as it could make the condition worse. Coughing is a natural protection to keep the airways clear and healthy. A common reason for persistent coughing are heart disease and this should be investigated as a priority. Honey can be used as a natural antiseptic and soothing barrier for the back of the throat but after more than one month your dog really does need a full health check

Q. My lab was diagnosed with kennel cough he put him on antibiotics but his cough is awful I’m scared for him Is there anything there anything for him
ANSWER : A. Usually kennel cough will go away within 2 -4 weeks. If his cough is so bad call your veterinarian and ask if he can give you some cough medicine for your dog, that will calm down the coughing. Since he has seen your dog recently he may have you just pick up the medicine, however some vets prefer to recheck your animal.

Q. My dog has been coughing now for a week mainly when she gets excited or barks she starts to cough. She is well eating showing no signs illness.
ANSWER : A. If she is around a lot of other dogs such as in a kennel, dog park or doggie daycare situation, it is possible she may have contracted kennel cough, a very common upper respiratory disease. It can come in both viral and bacterial forms, however only the viral form is covered by vaccination. The viral form usually just has to run its course while the bacterial form or any secondary complications may require antibiotics.

Coughing can also happen if there is an issue with the throat, lungs or even heart, and may be a symptom of a problem there. You may see other issues such as wheezing, gasping for air, changes in activity level (not as active, tires out more easily) in addition to the coughing. Treatment varies depending on the cause, and additional testing such as blood work or X-rays may be needed.

If the coughing does not resolve after a few days, if it worsens, or if you see other signs of illness, then scheduling a veterinary appointment to look for underlying causes is best.
