My dog's tail pocket has brown discharge. Is it an infection?

It may be a yeast infection and inflammation causing the skin to be thick and dark. This can also be caused by a low thyroid level. I would take her to your vet for a thyroid check and a skin sample to see if it can be resolved with medicines. If not and it gets larger then you would be looking at surgery

These look like little crusts associated with a skin infection. Your dog was probably chewing his tail excessively and caused the skin infection. If it is localized to only the tail he probably will not need antibiotics. You can try to use a topical antibiotic ointment on the area to help clear it up. If you cannot get it to clear up or if it begins to spread I would recommend taking Louie in to the vet to be checked out.

That is likely to be caused by a vaginal and perianal infection (probably secondary to a dermatitis in the perianal region). A check up is required to confirm this clinical suspicion and treat appropriately. Antibiotics and local disinfection with appropriate solution (betadine diluted should be fine) are likely to be needed. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

It looks like he might have a dermatitis/skin infection which could be secondary to allergies. You should check him for fleas to make sure that isn't the cause. He might also be licking his hind end because of an anal gland issue. You could try over the counter Vetericyn spray and see if that helps. If not, he needs to be examined and treated by a vet. He may need an antibiotic, corticosteroid, or other medications to treat.

It sounds like this is likely to be a cyst of some kind, but could also be an abscess, localized skin infection or some other type of skin growth - pus from an abscess would usually have an odor to it, but not always. You can clean the area thoroughly with warm water and soap, and it's fine to use topical antibiotic ointment like Neosporin as well. But in order to find out for sure what it is and get it treated more effectively, you will need to take your dog to a vet for an exam. He/she can take a sample of the white substance for analysis to help determine what it is, and will advise you based on the results whether it needs to be treated with oral antibiotics or other medication, or if it needs to be surgically removed.

He may have a skin fold dermatitis. Depending on what it looks like, he may need an oral antibiotic and/or corticosteroid to help treat the infection and inflammation. You could have your vet examine him to determine the best way to treat. I have never used Savalon but Mal-A-Ket wipes are helpful with skin fold dermatitis.

That looks infected. Pets can get infections like bacteria or yeast. Sometimes the infection is related to flea bites or allergies. You must protect the area from licking/chewing by having Denzel wear an elizabethan collar at all times. I recommend to have him examined by the veterinarian and he will likely get antibiotics, an anti-inflammatory (which will decrease the itching and make him feel better) and a medicated shampoo. If fleas are the cause, discuss which flea prevention is best for him. I hope this helps.
