Love it! So you have that same great view from the sunroom too - great planning
We have coyotes too, and they regularly pick off the cats. I've never heard of them getting a dog, but I'm sure they are capable.
Our friends in Arizona have lost two dogs to coyotes. They jumped the fence and attacked them. A knife is not going to be any help if a wolf or coyote goes after your baby. Smith and Wesson are your best friends in that situation.
I hear the coyotes every night where we live. Also see them every once and a while crossing streets etc. Not seen one in my yard fortunately! When I have little grand kids here I am always in the yard with them just in case. We just put in a sensor sprinkler for my garden - deer are eating my tomatoes, parsley grrrrrr
