Hi! I have a very active 5 month old Golden, Finley, that I need some advice on. Finley is a biter. He isn't biting out of aggression. He bites when excited and when playing with us. He hasn't broken skin, but has left many bruises. I've tried consistently with offering his toy, telling him "No bite!", and withdrawing my attention. None of this has helped. I don't know if it's worth mentioning, but he also is humping objects (his bed, stuffed toy, people) numerous times on a daily basis. I am not a novice with dogs. I have owned other furry family members over the course of 30 years of marriage - a Shetland Sheepdog, Beagle, and English Springer Spaniel, and now my Golden. None of these dogs have been biters. I am open to suggestions in getting Finley to stop his biting, especially once grandkids occur.
