Why does my 5-month-old puppy have pus bumps on Trifexis?

Poor Dash! Trifexis is generally a very good flea prevention so flea bites are not likely. Those spots could be several things including allergies, skin mites or a bacterial infection. You can try adding in an omega 3 fatty acid supplement for dogs, this can help improve the skin health. You may also try changing his diet to something like Royal Canin or Nutro as they are aimed at skin health. You can wash the lesions with soap once a day and rinse well (don't wash his whole body, just those spots). Protect the areas from licking or scratching. If they don't start looking better within about a week or if they get worse, have him examined by his veterinarian who may prescribe medications. Best of luck and please feel free to post any additional questions.

The bumps could be leftover reaction from her parasites, even a skin infection. The best thing is to get her seen by your vet for an exam and possibly a skin scrape to determine why she has these bumps and how best to treat them.

The age and pound limit for puppies is 8 weeks and 5 lbs. It would appear that Luna is within this range. The most common listed side effects for Trifexis include itchiness, anorexia, lethargy, redness and diarrhea. Often drugs may have other side effects that are considered uncommon and/or rare. There is also the possibility of allergic reactions to medications. If Luna appears to be in true distress to you, I would recommend getting her into a vet particularly if these side effects happened immediately after using the drug. Intervention may be required, and time is of the essence in smaller, younger patients. Hope this helps.

Thanks for using Petco Pet Education Center, formerly Petcoach! This is possibly due to allergies. It really comes down to figuring out what is causing his allergies so that they can be treated or the specific allergen avoided. A secondary infection is likely and also needs to be addressed. 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 then you are left out having to check for environmental allergies which require blood and/or skin tests. Allergies can be very frustrating to deal with at first but so rewarding at the end when we are able to treat them effectively!

Hello. This looks pretty typical for an allergic dermatitis that has lead to a skin infection. Ideally, this should be addressed by your veterinarian. They can discuss possible causes (food allergy, contact allergy, flea allergy, etc) and prescribe medications which may include antibiotics for the raised lesions and allergy therapies.

Pets can itch for many reasons. Trifexis is generally a very good product so fleas are unlikely though you can certainly check him with a flea comb. Pets can develop dry skin or allergies which can all cause itching. I recommend to have Buster examined by his veterinarian to start figuring out the cause and to get medication to help stop the itching. You can try adding in an omega 3 fatty acid supplement for dogs, this can help improve the skin health. You may also try changing his diet to something like Royal Canin or Nutro as they are aimed at skin health. I hope this helps.

That is an understandable concern. It appears he has a very bad case of folliculitis, which can be caused by several things including a Demodexx mite infestation, a contact allergy, environmental allergy or flea allergy. He needs to first go on a good flea preventative (Nexgard, Bravecto, etc) and then have a skin scrape/cytology done to look for possible mites. He definitely needs a short course of antibiotics to treat for his current skin infection and then medication depending on the results of his skin scrape/cytology. The vet should be able to get him on the right track if the skin testing is done. I hope this helps and best wishes with Trump moving forward. I hope his skin problems resolve very soon.
