Our vet recommended that bailey not venture to any dog parks until the age of 4 months. Our training instructor said it was ok after the second round of shots ( 2 months). We played it safe, and did not take bailey to a dog park until 4 months of age. In the meantime, I had mentioned that we made frequent trips to other peoples' houses. One of which was my friends' brothers apartment - where we usually went to watch the superbowl game each year.
Bailey met his first curly haired friend named "Cash". Cash was a older mix who didn't pay much attention at all to Bailey. Here they are enjoying themselves during a basketball game.
At this time, Bailey pretty much knew the phrase "go potty" and would go on command. His bladder strength was iffy, so I still took him out after and long bits of exercise or napping.
