This is thread shitting

Of course there are. Dogs are friendly, easy-going creatures who just want to play and to avoid conflict. Cats are evil, plotting, self-serving thieves.

The dog was no doubt instinctively protecting his Master from perceived threats. The fact that he may have smelled Cat on you may have exacerbated the situation.
The natural friendliness of dogs can be easily seen in any dog park, where the canines run around playing with each other! I’ve never seen that as a natural relationship among cats, and if it happens at all, it’s only after long acclimatization.
This is essentially a cat appreciation thread. Feel free to write about how much better dogs are than cats in some other thread. But please leave this one to the cat lovers.
