Is there a test for pregnancy for your dog?

There is no test you can give a dog to determine if she's pregnant or not. Unlike humans, there is no chemical change within the body of a dog. To tell if a dog is pregnant a very keen owner can usually tell very early on by mood changes. Also, dogs (just like humans) can have morning sickness early on. Then later on, of course, you get the more well known signs such as mammary development and abdominal enlargement. Dogs are pregnant around 63 days but can have them earlier or later than that.
