I just wanted to show some off some recent pictures of Hector. He's now down to 99.5 lbs which is too thin for him because now I can see some of the lower spine bones protude when he is sitting. Anyway, this gsd I am fostering really keeps him in top shape with lots of rough housing. The problem is that there is one spot on one of his foot that keeps getting rug burned. Then the other day I found an infection on his rear foot. If any of you remember, he was on a long bout of antibiotics for almost 3 months to clear a furuncle on one of his front foot and we had only finished like mid or end of Jan. Anyway vet put him on 3000 cepha and prednisone this time. I really don't think it's an allergic reaction to anything he is eating. He has no signs of allergies - clean ears, no itching, no signs of yeast infections. I wonder if he stepped on something in the yard or got pricked by the thistle weeds and then just opened up an opportunity for infection? Any insights or experience?
