Congrats on becoming a puppy mommy again! I'm sure over time Sweezy will love his new partner in crime/baby sister. I agree with everything Maximo said. It's always best to introduce a new pet on neutral ground. Lola and Teddy are littermates and we thought they'd be comfortable with sharing food together, but that's not the case. We have to separate them as Lola tends to push him out of the way and doesn't let him eat. I hope all goes well!
