hi guys, need some help as I am not sure if I am freaking out for nothing! My one year old cocker, Jesie went to the vet on Monday and we found out she had gastro. Vet gave her two shots, first was Amoxil second was Tribrissin. He also gave me some antibiotic tablets. Four to five hours after getting home she developed a rash under her arms, rang vet he said it was a reaction to the antibiotics but to keep giving her the tablets.
Today I've come home from work to find the rash is all over her belly. It's smooth but really red.
I'm a freaking for nothing or should I take her back to the vet?
Please help me!!!!!!!!
