Calvin is our gentle Giant. Calvin is gentle when taking treats and already knows sit. He needs leash training. He loves being pet and hanging out with humans. Calvin is a little shy and gets spooked when people raise their voices at him, so he's going to need a patient adopter willing to take their time building a relationship with him and set him up for success. Calvin can be a little picky about his canine friends, so he'll need proper meet-and-greets with them to set him up for success.
