My APBT/German Shepherd (please note that I spelled it right this time cliffdog). Has an issue with one other breed of dog.

I will preface this by saying that after becoming a member of this site, I no longer take Grizzly to the dog park. I exercise him with me and the only dogs he sees are my in-law's and my parent's under close supervision.

When I was taking him to the park 2-3 days a week he got along great with all other dogs. He played and chased every dog there. He seems to have a special affinity for the big dogs aka, Danes, bernese mountain dogs, kangals. But he has aggression issues with labradoodles and golden doodles. whenever he see's one he becomes a bully. His body posture would change and he would become more aggressive with them, prompting me to leave as soon as one came to the park. It didn't get better even after I tried to socialize him with several of them.

Has anyone else seen this in a dog before.
