Yep. I have a 13yo maltese shihtsu. She used to be fine on her own. Then we got a staffy x kelpie and my partner refused to leave him at home. To start with it was because he was a puppy and he didn’t trust him not to destroy the house. So the little dog ended up coming out with us all the time too. Now, the maltese is still OK home alone but the big dog does not cope at all. It’s frustrating as it affects how and what we do as a couple. Eg we had my son, dil and grankids visit recently. One of us had to always stay home when outings were organised cos of the big dog. I didn’t mind that as I was the one going out.
