I currently own 3 GSD's two of which I have had since puppies, the third is the one im having a hard time with... Max is a 2yo male he is the brother of my other two GSD's. He was abandoned when acousin of my husband's moved to Florida. He called us on his way there and told us that we could have him if we wanted him if not someone would "take care" of him! I was furious, anyways we went over to the house and the dog was terrified. He has never been socialized, never wore a collar or leash, wasn't fed on a regular basis. Among other things, we had to call the dog warden to tranquilize him just to get him home! I have had him for about 2 months now and he has made a complete turn around, he gets along wonderfully with my girls he lets people pet him, and has even started rolling onto his back for me. So the problem I have is a good one and a bad, where no one ever paid him any attention he gets so incredibly excited it makes it very difficult to train him! He weighed 103 lbs at his last vet check up and is solid muscle, I'm thrilled that he is so happy now but I want to move forward with training and his size nd strength makes it very difficult! My females have been with me since 8 weeks old and im find mg out that there is definitely a huge difference in training a dog and a puppy! Any tips would be gladly accepted, thank you in advance!
