My poor baby had a swollen paw a few days ago. She has lots of allergies so we took it easy, took some Benadryl with lots of peanut butter, and the swelling went down as normal. Tonight I noticed some discoloring in her paw and found a large blister. She isn’t favoring it or even pulling away from me while touching it. Any ideas?? ?? calling her vet first thing in the morning but wondering if there is anything I can do in the mean time. I feel AWFUL. ? Please help if you can.
