Hi there and thank you for using pet coach to address your concern. With the description you have provided I would recommend having her see n by your veterinarian to have testing done such as blood work to see why she is lethargic and vomiting. The skin condition would likely not cause the vomiting. Your vet may recommend a course of an oral antibiotic and topical therapy for the skin condition. I would also have the cysts tested to see what they are. Your vet can insert a small needle into the cysts and see what the cells are under a microscope to help determine what they could be. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns. I am also available via consultation if needed.

    I am not sure if the skin and vomiting are related. Common causes for the skin issues you have described include bacterial infection, fungal infection, mites, fleas, allergies, among others. The pus indicates either infection or an autoimmune issue and she will most likely need oral antibiotics to fix this problem. Possible causes for nausea include dietary intolerance, dietary indiscretion, food allergy, intestinal parasites, GI blockage, gastroenteritis, bacterial or viral infection, IBD, pancreatitis, among others. If the vomiting or inability to eat food continues for 24 hours, I recommend that she see a vet as soon as possible.

I have a 7 year old female German Shepard. we have seen several vets and still have no answers. She in the last year has been suffering from fatigue, localized itchiness , reoccurring yeast infections, appetite loss, and frequent vomiting. I have cha
Thanks for using Boop by Petco. It sounds like we may have two separate problems- a skin problem and a GI problem. The skin itching could be related to food but is more likely related to environmental allergies (which can develope at any age). Another possibility is that it’s actually pain- she is the right age for arthritis and other problems. This may be especially true if it’s over a joint. A foreign body like a thorn stuck in the skin is also possible. For the vomiting, there are many many possibilities. Acid reflux is more common with age. A trial of small frequent meals and Pepcid AC (famotidine) can help. Other possibilities include long-term foreign material (cloth or object swallowed long ago), organ disease (kidney disease, pancreatitis) cancer, and more. Abdominal xrays, full blood work, abdominal ultrasound, and sometimes even an upper GI scope or exploratory surgery may be needed to figure it out. This is a complicated and involved case and we could definitely talk

My dog has two bumps under her skin on her back. She is a German Shepherd, and is 7 years old. She barks a lot, and has been biting at one of the lumps located on her back. She has been puking a few times a week. She has anxiety, and has had Lyme dis
I am sorry Brie is not feeling well. I would recommend taking her to a vet to have the lumps examined closer. A vet can place a small needle into the mass and look at the cells under a microscope to determine what the masses are. Masses can range from cyst, abscesses or even cancerous so they should always be checked out. Also since Brie is vomiting it would be best for her to have an exam and maybe even abdominal x-rays to determine why she is vomiting. IT is important to make sure the mass and vomiting are not connected. I hope brie feels better soon and thanks for using pet coach

My dog has been scratching for over a week. We remove the ticks off her body but she continues to scratch. She also have bump on her face and private area. Also she has been vomiting yellow. I just got here 2 weeks ago and dont know what to do.
Hi, and thanks for your question. This could be due to an allergy, although it could also be infection or mites. First of all, in order to rule out skin parasites, you will need to treat with a high quality flea treatment, then ask the vet to perform a skin scrape - this might reveal an infection or a mite infestation. If all of those came back negative, the next step is to treat the allergy symptomatically and try to discover the cause of the allergy. Three main type of allergies are usually affecting pets: food allergies, flea and parasite related ones and environmental type (allergens coming from trees, pollens, dust etc etc). Some medications can be given by the vet in order to repair any possible skin lesions (like steroids and antibiotics).

Hello I have a German shepherd female that started with a red rash that looked like dry skin in her armpit. It has now spread to her stomach and backs of her legs. We thought it was an allergy but I am not sure now
Hi there, It looks like Blair could be having an allergic reaction as you suspected and now she has a secondary bacterial infection. I would recommend you taking her into your vet for a skin test. They can find out what is causing the rash and also get her started on medications to clear it and make her comfortable. I hope that helps and thanks for using Pet Coach!

Older dog has skin lesions and they bleed and are sore. Recently.ill and through up several times and could hardly walk. Area in question was very painful. Was in good health till today.
Thanks for using Boop by Petco! This is possibly due to allergies though other things like mites are also possible. It really comes down to figuring out what is causing her allergies so that they can be treated or the specific allergen avoided. If she is still vomiting, that should be investigated further. There are many things that can cause allergies though in most cases they can be broken down into 3 big categories: flea, food and environmental allergies. Allergies are usually worked up in a stepwise fashion starting with flea allergies as this is the easiest and cheapest to take care of. If not on a flea preventative, then it would be a good idea to get started on one. If already on one then it would be a good idea to change to something else (there are many new products out in the market). If not improved in 1-3 months then it is time to move on and check for food allergies by switching to a novel diet (new protein and new carbohydrate). If that does not seem to be the issue

Hi my dog has vomited bile for 4 days, had an allergic skin reaction for 2 days 2 days ago, and has chills
Hi, and thanks for your question. These signs could be compatible with an inflammation infection of the gastrointestinal system and surrounding organs (like pancreas and liver). It is difficult to say if the allergic reaction and the gastrointestinal signs are related at this stage (probably this is an alimentary allergy). A clinical examination at your local veterinarian is immediately essential to confirm these clinical suspicions and treat appropriately. Antibiotics and possibly further investigations (like abdominal imaging as ultrasound or radiographs) may be needed.

Hi, do you know what happened to my dog? He just came back from vet 2 days ago and doctor said he having sensitive skin due to his food. I just saw this red bumps growing bigger few mins ago.
Hi there and thank you for using pet coach to address your concern. Judging from the photo, the skin does look abnormal and could be related to an allergy or sensitivity. However, the large red bump you are referring to looks more like a tumor / mass. This could also be an abscess and needs to be treated and have further testing performed on it. Bolly may need a course of antibiotics for further treatment and I would also see if your vet can perform some additional tests on the bump to make sure it is not a cancerous tumor to be concerned about. I hope this helps! Please feel free to contact me with any further questions or concerns you may have. I am also available via consultation if needed.
