My 4-month-old puppy has a rash, hair loss, goopy eyes, and low energy. Why?

Updated On September 23rd, 2025

Pet's info: Dog | American Pit Bull Terrier | Male | unneutered | 4 months and 11 days old | 10 lbs

I have a 4 month old American Bull Terrier. He was in a little bit of bad shape when we adopted him. After being thoroughly dewormed, slowly gained needed weight, he is doing so much better. The only issue we seem to have right now is a skin problem. He has a red bumpy rash all over, has a little bit of hair loss but not too much. Is itchy but not to the extremes. And since this began his eyes have been gooking up more than usual. Also a low energy level for his age. Any advice would be great.

Hi there and thank you for your post! I'm sure Ruger is a cute puppy! It sounds like he could have one of several possibilities. With his age, I would certainly be concerned about mange / skin mites. His immune system is still underdeveloped, which predisposed him to getting skin mutes such as demodex a lot easier. He could also have a skin infection Or allergies. In any case, I would get him checked out just to ensure that he doesn't have a skin parasite or an infection that needs targeted specific treatment from your vet. Please let me know if you have any other questions or concerns.

    Also, his eyes having discharge may indicate an eye infection that might require antibiotic eye drops. If he is quiet and not having much energy, this could be due to the problems he is currently dealing with. Again, I would see about scheduling an examwith his vet to get him treated right away if needed.
