Alfie is a very energetic puppy. He is super playful and has endless amounts of energy. He is either 0 or 100. Nothing in between. He loves playing and is quite boisterous, but never aggressive to people. He loves playing with his ball or his frisbie. Any sort of interaction that requires him to get something and bring it back to you.
Alfie has exhibited some unwanted behaviour towards other dogs (male - entire) and has displayed some guarding behaviour to our other dog in the house. This is not consistent so we are trying to figure out what the trigger is and how to address this behaviour.
