LOL– I def know how hard it is to be on a computer... the phone... or do anything with a young B vying for your attention!
Ava was very petite, too. I was actually getting worried about her-- then she just grew, almost overnight! She's 16 lbs now and 15.5" tall. No more baby!
My thinking is just like yours on the spaying. I want to wait as long as I can, but I don't want Ava going through a first heat. The vet said she could have an early heat any time now, so I'm thinking about having her spayed in the next few weeks. That's what everybody is recommending, though I would rather wait. Ava has a hernia, too, so we're repairing that as well. She also still has a lump from her rabies shot, so we may have to look into doing something about that, too.
Ava's progressing on her crate-- lots of dissatisfaction and B outrage, but less wild panic. It's slow, because I couldn't bear a setback. Housetraining is better, too, but she HATES to pee on the grass. In the middle of my landscaping, on top of a plant-- particularly temperamental plants that I'm especially fond of-- is her preferred place of elimination. It's better than on my carpet, but not by much. How's Kaia's housetraining? She was much easier, I bet, with Loki to help her along. And how's the nipping/biting? Ava's cutting molars, and those jaws are like a shark seeking prey.
