Pity you don't know his pedigree, handsome dog none the less.
Flynn and Tulsa have very similar coloration.
Tulsa is very prey oriented, and will chase squirrels before she will play with others at the dog park.
She cruises the perimeter of the park looking for trangressors, and stalks them. Only when the 'puppies' interupt her hunting will she play. She's getting very 'Cranky' in her old age!
She's almost 4 years old, and has 'issues' when I pay attention to other dogs. She will lie at my feet and pounce on other dogs that come up to me. Not aggresively, but just to tell them that she is the 'Queen', and that they should ask permission!
