Cooper in the pic

I need help
Serious help
Actually not really at I just feel sad :(

Ok so my brother's moving and he's leaving is with his calm cool cat Shelby though you may know her as Brightcloud

Shelby^^

My dog Cooper, who is almost eight years old now, isn't so happy that she'll be living with us, even if it was just a babysitting by thing (which it is not)

The thing is when I was at my cousins for a few days with Cooper they had a not-so-dog-friendly cat.

^Emmy (cousin cat) hiding from Cooper

When my cousins cat hissed and slightly swiped at Cooper, he completely freaked.

Growls, jumps, barks, and clawing came from my dear dog- which is incredibly unusual behavior for the lovable dog he is

Now, Cooper does this whenever he sees Shelby and he chases her

Shelby's fine- just camping out in the bathroom and she seems pretty happy exploring the room when I check on her.

It's just, I hate how Cooper hates her :( 

And the thing is we don't know how long we're having Shelby for, and it could be for a long time....

Which is a yay though cuz my (other) brother and I love cats 🐱🐱🐱

That is Brooklyn my brother's (the one that's moving) Shiz Zu Poodle 3 month old puppy <3
SHE is good with other animals including cats -_-

And THAT is a male gorilla from a zoo

Aaaaaaand Cooper is chasing after Shelby again \_(•~•)_/
