Recently visited a friend with a dog which they have had from a pup, which has had no training, its a big breed and the experience made me re think getting a pup.
However my other friend visited my house with their dog which has had training and it was am amazing and happy experience. The dog was so happy and well behaved. It doesnt do tricks etc just a well behaved dog.
so really made me realise that if you put the work in you will reap the rewards
