No, we never did the dog park with Mally. I believe we should have, as it would have helped Mally in his socialization. Mally loves us and some select people and his best friend, Crede (shizu-poodle) in the neighborhood. We walk each morning with Crede and his mommy, but we now have to walk slower and have short walks because Mally has arthritis. Crede still runs in our yard and Mally catches her on the way around and they still tossel (play fight). Crede takes it easy on Mally. They play tug too sometimes,in the yard. Also, they will relax in the yard and chew on rawhides. Mally had Lyme disease when he was quite young from and infected deer tick. This brought on his arthritis at an early age.
ps Mally does okay now with Pogo the dog we watch periodically. (But they are not great friends like he and Crede are).
Note:There is a picture of Mally and Crede on Mally's picture album here on the forum.
