Hello everyone- It look like Diego may have been stung or bit by something, and I wanted your advice. On walks he has his noise in the groung 75% of the time, so he could have easily been stung/bit. I first noticed the redness around his nose yesterday, and yesterday morning he killed some kind of small animal (mole?) that was in the ground because I heard it squeeling.. the first picture is what his nose usually looks like, the second and third are each side of his nose this morning. He didn't itch his nose last night, but this morning I caught him itching it with his paws and on the carpet. I started him on benadryl last night (1mg per pound of body weight) Is there anything else I can do? Does this require a trip to the vet? If it doesn't, how long should I wait if it doesn't improve until we visit the vet? Thank!!
