Oh man! Heat. I've never gone through one with a dog, but maybe a call to the vet or breeder would help with knowing if anything needs to be added to the food.
But you could call them either Chihans or Afhuahuas and sell them for a small fortune:thumbsup: It'll be a totally new "breed" I googled the mix and didn't see it listed so you'll be the first one to produce them, you can call them a "rare new breed".She is such a high strung dog that we have problems getting her to eat to begin with. Both her and Cora are "nibblers" which is a total pain in the rear end. So far there has not really been any behavioral changes but it is just the first day and I'm not sure I would expect them as of yet.
We do kind of have her penned up like some maiden in a castle though! When she goes out into the back yard she goes into a 6 x 8 covered dog run that is behind two other fences.
We have a lot of stray chihuahuas here and the absolute last thing I want would be Chihuahua/Afghan hound mixes. How awful would that be? ew
