Rose am kinna laff'n here coz I remember... when Shuggabear came to me at furst.. she really was clueless. I had a small dog already (Sweetpea) who was smallest but she was the BOSS haha.. Wellll it was kinna nutz for a few weeks but then it all shook out. They decided the peck'n order and I jus made sure they knew momma loved um both equal like.
With catz in the mix it might be a lil chaos but maybe you can keep the new pooch behind a child's safety gate (you can find them at Goodwill for nex to nothin) until he sees the catz an they see him. Eventually he'll get to be loose with them and sheese.. catz can escape. Here there is one male cat (Odie) and the two lil doggies act like they are gonna eat his lunch but it's all a game. Sometimes I've eased up to my son taking a nap in the ez chair with the cat on the arm an the two dogs on his feet an lap
.. Maybe at meal time you could make sure the lil dog has time to eat without the kitties there to make him anxious. They wait all day til meal times.
I wish yas the best. Love conquers it all doanchaknow. Kitties an doggies can live together. It's all good!
I forgot to say this too.. At Walmart you can git a small doggie plastic crate. He can have his pilla an blankey in there an it's HIS cave. He can be in the room where you're watching tv or sleeping or whatever and See whas going on quietly. At nitetime you can say "Git in your bed" and lock the lil door and not worry about the kitties. If you go out he can wait in there for yas an you won't be anxious about whas going on at home. The minute you let him out.. take him outside to go potty. Ya'll will figger out a good routine.. Good Luck!
