A month ago, I temporarily brought in a puppy home, which was one of six puppies born to Teri - a Wire-Haired Terrier. Being a male, this puppy was very dominant. I figured it would be enjoyable for him - and educational to Max - if they interacted with each other. It took less than ten minutes for them to warm up to each other. Initially, Max had no idea of how to begin, but the hyperactive puppy made the ice-breaking process easier.
It did not take much time for these two dogs to playfight. The duration of sessions were not short. That is because the puppy had all the energy in him. There were occasions that Max avoided the puppy because he was exhausted.
The puppy was with us for one week until someone adopted him. On the first night when he was gone, Max was depressed and listless. For three days, he would come into the house and sniff at the cage, as if hoping the puppy would appear.
Nevertheless, it was an important event for Max, as it was his first physical contact with a dog.
