I have a 3 yr old maltipom, she was bred April 28, 30 and possibly May 4, 2009, I paid the breeder for the mating session yet I cannot tell if my dog is pregnant or not. She tied once on the 28th and twice on the 30th and possibly once on the 4th of May. Her nipples grew but very little. She lays around and sleeps all day when she is not cleaning herself down there. Her vulva is still purple but it went back down to normal size. I keep finding her hair on my carpet. If she is pregnant she would be 59 days today, her belly did not grow or anything could she be pregnant with just one or two pups or is this a false pregnancy and I need to get my money back?
