MikeT66, I believe shelby means everyone ELSE will blame your rottie; Who would ever blame a sweet looking golden or lab
.
I do take Nisha to dog-parks on a regular basis...the main reason I go is b/c of the wide open, leash free space
!! Nisha only plays with a few dogs she has know since birth (well...8 wks); we call these dogs her "cousins" (family members dogs).
At the dog park, Nisha tends to ignore all dogs. She is 100% focused on the Frisbee, or Tennis Ball. Also, our dog park is on "Town Lake", so she swims too. Dogs often "invite" her to play, but she ignores them...always has...always will.
I have very good control over Nisha, and her recall is almost 100%. I would not feel comfortable unless this was so.
