Thank you all, this is great advice your all giving me. I like the idea of training one outside while the other is crated, they still pull hissy fits but it's more tolerable. I live in Massachusetts and we've been stuck in this nasty weather pattern for quite a few days now, so it's very hard to take them outside to work, too much mud in our yard right now. I do take them for walks, one at a time. I live in a small ranch which makes it pretty hard to work with the two of them in the house, but I do try and will keep working on it.
I'm having a very hard time house training Maisie. I take her out religiously but the little devil will smell around outside for the longest time and I think that she doesn't have to go, so I bring her back in the house and low and behold....she goes..
I thought about training her to the bell but decided against it, I don't want them both ringing the bell just to go out in the yard and play, and I'm pretty sure that's what they'll do. Funny, Maisie has never gone the bathroom at all in her crate. When Tess was little, she peed in her crate a number of times but she has excellent house manner now....thankfully!
Some asked for a photo of the two of them together, hopefully I remember the right link to post and they come out okay.
Here's one a few days after Maisie came to live with us, she's giving Tess a dental exam.
Here's one of Tess giving Maisie enough room to stretch out. Notice how Tess is cramped in the corner. Maisie refuses to believe that she's a little dog.
