What do I think? You'd have to be a muggle to buy a puggle. I would suggest going to a rescue with your daughters and finding a dog they both like - instead of lining the pockets of an unethical breeder.
Sorry for chiming in to this thread so late, but I just had to share this in case it helps someone out. I wish I had gotten this advice years ago. Training your dog really is the only long-term solution, OP. I love my dog so much but it constantly did the things that irked me most. It would chew on things that it shouldn’t or jump up and down out of the blue. Whenever I put on the leash, it would pull on it. Whenever it was out of the house, it would continue digging on the ground - I wish I could tell what it was looking for down there. The same goes for all the nasty urine. All the things it did left me feeling depressed as if I failed it monumentally. But since I discovered Brain Training 4 Dogs and applied the system offered, it now behaves the way a beautiful dog I always expect of. I highly recommend it. [removed]. a link to their site. Good luck!
