I have a 2 year old female pure breed yorkie, and i also have a male 11 months yorkie. My female yorkie was inheat and they did it, and he got stuck to her. and now a month pass. Her nipples are pink and very big, she gain some weight and her stomach seems to be a little bigger and when i poke and feel on it, it feels like there is alot of water in it. but i am not sure if she is pregnant. i want to know is there some home remedy or something that i can find out, i dont want to go to the vet because it might cause alot of money. please help!
