I first saw this rash on Murphy in September (2nd to last picture). This was a few days after getting his stitches out after being fixed. The vet said it was just irritation and could be from an allergy or bug bites or fleas (he does not have fleas). The vet prescribed Gentacalm which I dabbed on his rash once in the morning and once in the evening, and then the rash went away within a week. 

About a week and a half ago it started flaring up again (2nd and 3rd pic), so I started using his Gentacalm spray again. The rash has gradually gotten worse until reaching the state shown in the first picture. 

I will be calling the vet tomorrow morning, but I really want to know what I should be expecting, I don’t want them to blow it off as “fleas or grass”. 

The rash is a little warm, elevated, and is kinda scabby. It was not scabby last time it came. He tries to itch it sometimes but not often so I don’t believe it is very itchy. The black dot shown in the third image was not present before this flare up. Murphy’s routine and diet have not changed throughout this time. (Meaning since he got fixed in August).

The final pic is unrelated, Murphy has these weird ball shaped things at the base of his penis that only show up sometimes (no rhyme or reason). They started showing up after he was fixed. Could this have something to do with him getting fixed? He also had an umbilical hernia when he was a puppy <4 months (he turns 1 this Friday), but it “resolved itself” before I got him. (He was checked by a vet the day after I got him and the vet said it was gone). 

Thank you so much to anyone who may have advice or ideas of what could be causing all this!
