I have a boxer mix, and lately she has been getting a LOT of skin rashes - and tonight she got welts. We just changed her dog food to 'Canidae' and gave her some yesterday and last night and this morning my mom said she looked and her skin wasn't bad. And then tonight she had a big rash and welts - which she has NEVER had welts before.
Any ideas? Any help is appreciated - I am kind of freaking out.
