UPDATE! So after I stopped feeding Remi the fromm, the rash ended up getting worse over the weeks. I didn't notice because I was sooooo down for the account while recovering from the appendix surgery, but after a trip to the vet, they fixed him up for us. She said it looked like contact dermatitis (long grass. I'm pretty sure @cali_baker called that!) with a few spots of ringworm. He's on antibiotics, a special shampoo dip, and anti-jock itch cream. I'm fairly certain the people at Walgreens thinks my husband is suffering from something. HAHAHAHHA!
Once this is completely gone I'm going to attempt to switch him back to the fromm. Cross your fingers... But he's looking great. In fact the vet said, "he's a great looking bulldog. I haven't seen one look this good in a while. His ears look great."
