Why is my 7-year-old dog losing fur in clumps and having diarrhea?

Poor Shaggy! This vomiting, weight loss, and dull fur could be due to a heavy burden of intestinal worms. It could also be caused by a medical illness such as inflammatory bowel disease, chronic GI illness, or a foreign body among others. I would take him into the vet for a physical exam, blood tests, fecal exam (bring along a sample of his feces), urinalysis, and possibly x-rays. Using these tests, the vet can diagnose what is causing Shaggy's symptoms so he can be treated.

I don't think this is seasonal shedding. I would be concerned about causes of hair loss and itching in a puppy, including fleas, mange, lice, infections (bacterial or yeast), and ringworm. A vet examination will be able to help you figure out the cause and best treatment. I would also discuss the diarrhea with the vet. Possible causes include food intolerance or allergies, intestinal parasites, dietary indiscretion, bacterial or viral infection, stress colitis, among others. Even though Bear was dewormed, the vet should probably do a fecal floatation test to check for intestinal parasites.

It could be that Munchie has a skin infection or a fungal infection causing his fur to fall out in chunks. It could also be due to fleas, mites, ringworm, or a hormonal imbalance. You need to take him into the vet. The vet can diagnose what is causing his hair loss, and can treat him for it. I'd call his vet first thing in the morning to make him an appointment. Best of luck, I hope this helps!

Those are all very general signs of illness, and I would be concerned there is a GI issue or underlying illness if she is both losing hair and unable to keep food down/losing weight. Parasites, obstructions, viral illnesses, infections, organ issues, metabolic diseases, etc can all be potential causes, so it would be best to seek out veterinary care from your vet or an ER clinic as soon as possible.

Hello and welcome to Petco Pet Education Center, formerly Petcoach. Weight loss can be a sign of intestinal worms, organ dysfunction or disease (pancreatic insufficiency, liver shunts, kidney disease, liver inflammation/infection, etc.), food allergies or poor diet, and many other conditions. Hair loss can be due to parasites (mange, fleas, etc.), hypothyroidism, allergies (food or environment), immune diseases, etc. Given that Kalu is 2 years old, I would start by getting him dewormed and also get a product that treats for fleas, ticks and mange. See if his problems resolve. If they do not, then see your vet about testing. Best of luck with Kalu!

There could be a couple of reasons why Diesel is losing hair on his stomach and armpit. He could have a skin infection causing the hair loss, or could be suffering from Cushing's disease. It could also be that he's very itchy. Severe itching can be caused by fleas, mites, ringworm, or allergies. If he isn't up to date on his flea treatment, I can give you one for him. First, I would give him Capstar. It's a one time pill that starts killing fleas within 30 minutes. Then follow up with a spot on treatment, such as Advantage or Revolution. This is a treatment that has to be used once a month. You will also have to disinfect the environment. Wash his bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home. If he is up to date on his flea treatment, I recommend taking him into the vet for an exam tomorrow. The vet can do blood tests, skin scrapings, and use a Wood's lamp to diagnose Cushing's disease allergies, mites, and ringworm. The vet can also check to see if he has a skin infection. Once the cause of the hair loss is found, the vet can prescribe the appropriate treatment. I would give your vet a call to set up an appointment. Best of luck, I hope this helps!

This may be due to parasites (fleas, mites), infection (bacterial or fungal) or allergies. Lucero would need to be physically examined by your veterinarian to diagnose the underlying cause. This may take diagnostics such as skin scrapes, cultures, allergy testing or food elimination trials. In the meantime, place an e-collar (cone) on him to prevent licking or chewing. Treat him for fleas, even if you don't see any, using a topical or oral preventative. Treat monthly for 3 consecutive months, preferably year round. Treat the environment as well by vacuuming everywhere and washing all bedding. An area treatment, such as Knockout ES or Indorex, should also be used. If Lucero has allergies, they can be frustrating to diagnose. Discuss allergy testing, hydrolyzed diets, food elimination trials and antihistamine use with your veterinarian.
