Hello all. Rosie is a 7 1/2 month Ruby. She is a rescue pup who came into our lives 8 weeks ago. While we are working through many puppy issues the one that I need help with is correcting her biting. She will try to use my hand as a chew toy which is corrected with a "no" and I switch out my hand for a toy or bone. Lately this is has become more of a snap and a less playful bite. I have continued to say a firm "no" and give her a toy / bone. Am I doing the correct thing? This is my first puppy/dog so any suggestions on how to correct would be helpful. I'm so pleased to have found this wonderful site!
