German Shepherds are glorious protectors, they love being part of the family unit.

Seems like she wants her buddy there.
Does the dog feel the need to protect them at all times?

What a good boy. What was so important that he had to leave? And I agree, I found the giggling annoying.

At least the man was very gentle with the dog. I'll give him that.

That's what Mama Cat seemed to be saying, too.
Thank you.

Trying to forcibly separate the "family" is a good way to get bitten. When the dog's ears go flat, it means it is getting pissed off. This video isn't cute, IMO, leave them alone, the pets were all happy there.
