Hi, We're due to collect our new Doberman puppy in a couple of weeks. We already have a dog (a greyhound) and have had dogs in the past, but we've never had a puppy before as they've always been rescue dogs. I've been reading that you should be careful not to over exercise a puppy as it can damage them as they are growing. So, I'm wondering how to work out how much is too much? Is it just a case of watching them to see if they are getting tired or should I limit the walk to a few hundred yards and do this 2 or 3 times a day? The puppy will have had both vaccinations when we collect it, so as I understand there should be no problem with going out. Thanks Jo.
