Please help!! My 4 yr old pit has a bad bad rash on his private area & his arm pits. His private part as of last night is now swollen.
When it first started it was just a couple round spot on his inner thighs, almost looked like ring worm. But it’s not because my other two dogs(also pits) don’t have anything wrong with them. Anyways I started giving him a bath with universal shampoo, & it looked like it was helping. But over the past two days it has just gotten all red every where & now his private area is swollen. What can I do to help him?? Last night I just cried for hours cause I felt so helpless…
