My dog had surgery. Why are his hips tender, tail red, and blistered?
Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. This appears to be an old wound that is healing. This could have been secondary to a burn. Sometimes when heating devices / objects are used during surgery, these can cause a blister if left on too long. I would contact the veterinarian who did the surgery and ask him / her if any heating objects were used in this region. It looks as though it is healing well so I would just monitor it for now and if you notice any signs of infection (swelling, redness, pus, pain) I would have the veterinarian assess the area. As for the tail, I would recommend using a topical medication such as Zymox topical ointment to apply to the affected area 2-3 times per day until resolved. If there is no improvement, I would recommend having the tail assessed by the veterinarian so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
