I am a two-time sheltie owner. My previous sheltie got horrible dry/itchy spots on his belly. We thought it was allergy-related, perhaps persistent fleas, and we were even told there may have been an underlying immune system issue. The poor thing did have a lot of physical/health issues. Our current sheltie, who we adopted in April at 5 months old is a beautiful sheltie- wonderful temperament, thick-boned, HUGE (already almost 40 lbs), and already has a nice, full coat. However, he, too, has developed those same dry/itchy spots! He IS shedding right now (blowing coat, I'm assuming), but he's scratching and biting a lot too (no fleas). Now that we've had an unhealthy sheltie and a seemingly healthy one, I'm wondering if I'M doing something wrong. The diets are different, so I don't think it's that. I'm wondering if it could be something in the house? Or a way I groom? Moisture? Humidity? I live in Syracuse, NY-- very humid summers, freezing winters. I'm at a loss. I've heard shelties are notorious for skin issues but Henry seems so healthy (Miles was very sickly). Any insight?
