We think the combination of scuppers allergy to grass and the hot asphalt caused some minor paw injuries. Most of his pads are fine, maybe slightly red, but his back right paw was really raw. We called a vet, Dr Berdugo, with Island Paws. Surprisingly she came out to us. We met her at the dinghy dock and she examined scupper up in the laundry room where there was a nice table for her to work on. She gave us some antibiotics, some topical spray, and some shampoo. She was really great, spent quite a bit of time with us, very reasonable prices ($150 for visit and all meds) and scupper has shown dramatic improvements by day three( whew!).
Before his paws were an issue I had ordered this ointment to help protect his paws from the hot surfaces of the docks, roads etc. but I had not used it yet. I was using Bag balm at night as a moisturizer. Only drawback to mushers is it attracts dirt. So scuppers paws are black after a long walk downtown Key West.
This is the paw booties he uses. They are disposable. I like them because they are fairly thin and breath. Most paw booties are pretty heavy duty which is overkill for what we need and way too hot for scupper. I was also concerned those booties would promote fungal growth. The cotton disposable booties, bandages really, are only worn right after scupper gets his paws sprayed with medicine. I remove them after about 15-20 minutes. For outdoor walking we keep to shady sidewalks and carry him whoever we walk over asphalt or sketchy looking surfaces.
This is called Coban, it is great stuff as it sticks to itself but not the skin/fur. If it come to the point where I need to wrap his paw for walks I will use a combination of cotton bandage and Coban.
