Our puppy is now 5 months old. He is house trained and understands "NO", and "Sit". He goes many places with me although now it is getting difficult. He likes to pull me now. He is a boykin spaniel and weighs 26 lbs. We go to the pet store and he just does alot of sniffing, and we go to the dog park and he plays well with others. Where it gets tough is when I walk him to my daughters school waiting for her dismissal. He just pulls, pulls, pulls! I tell him no and pull back but I don't want to hurt his neck, he is already hurting it by pulling so hard. I want my puppy to eventually be a therapy dog, but what can I do until I have money for proper training? Do I need something other than a regular collar? Boone is smart, sweet and very eager to please.....
