I think there are pro's and con's. I've been trying to convince my hubbie to let me get another. I work from home so Jaxon isn't alone too often. But I think he'd love a little sister to play with, plus I'd get to dress her up.
Hubbie says - double the vet bills, double the food, double the cost when traveling (by plane), and double the poop!!! I am still working on him as this stuff doesn't seem bad to me. Just not sure how I'd fit another Yorkie on my lap while I'm working.
