question: I have a Great dane who 2 days ago had a swollen foot,,,No puncture wounds no obvious wound. Thought maybe spider or bee sting. Soaked foot in warm water and Epsom salt, swelling went down but last night dog chewed a hudge hole on the top part of his foot. No tissue to suture together. On Antibiotics but wondering what I can do to get it to granulate in? Worried about infection??
