I think this is very normal! When they figure out the other dog is staying they pout. Thats what Goldie did, she wanted nothing to do with Stogie, they played at first then she just pouted.
She would get on the other couch by herself anytime I pet him. Before long, they will be best buds and play all the time. I do think Havs get along with each other. I cant seperate my two now. Hang in there!
The new pup is cute by the way. So is Reece! ( Thats the 10 month old, right?)
