chi’s can have terrier tendancies, but mine were very well socialized from pups (except chiclet i rescued her from a backyard breeder, she’s so sweet natured cause she thankful to be out of her situation and has become happy go lucky.) since i’m a vet tech and have helped rehabilitate various species i was confident that the meeting would go well. i wouldn’t leave them all unsupervised together though. accidents happen, and when the chi’s get to doing their zoomies (the chihuahua binky lol) they could run right over iorek and jumba is the larger of the chi’s he’s almost 7 pounds, the girls are 3 1/2 and 4 1/2 pounds. i usually don’t have all of them in the ex pen at once either, i had to have chiclet in there while chiwi was with iorek though (chiclet has a bad knee and she’s painful so she’s been clingy to me.) i’m also in the ex pen with them too. it’s a very controlled environment.
