Is my dog pregnant?

My dog is a Siberian Husky and we kinda saw her humping this other dog but we don't know if she's pregnant or not. It's been 2 months and shes growing t**s but yesterday when we saw her she looked thiner and today we saw her again and she looked fatter.

take her to a vet better be safe then sorry im only 15 going on 16 when I get outa highschool ima go be a vet tech hehe the growing t**s I say she could be

WAS SHE IN HEAT BECAUSE IF SO SHE'S PREGNANT

Well one way to tell is feel her stomach if it is hard and if she is getting t**s then she probably is it's not really a big deal dogs usually do what they need to do just make sure she has pleanty of food and water and maybe some milk she will be fine and a place to lay down that is all her own give about three more weeks and you'll be able to tell for sure!

If your dog is laying on its side and youre scratching her belly, her legs ont be together and her genetile area will look slightly reddened. Also, bigger t**s are a huge sign she is pergnate. to be sure, bring her to a vet and prepare for arrival!
