pregnancy in bull terriers

Question
How long will it be if a bull terrier is currently leaking or has spits of milk coming from her nipples to determine if she's pregnant or not?  If she is pregnant, how long before she's has them?  

Answer
Hi Jay,

The gestation period for dogs is anywhere from 59 to 63 days on the average. I can't say when your dog would have her litter, you didn't say when she was bred.

From the fifth week of pregnancy on, the nipples and mammary gland increase their size and get darker, getting ready to receive the puppies. Your dog may seem a little more quiet than normal, but apart from this nothing on its aspect indicates its pregnancy up to the sixth or seventh week, when its abdomen begins to progressively increase as the puppies get bigger in size. Your dog may need to urinate more often than usual.

In the eighth week, the dog's breast, which are really big already, begin to secrete whitish and transparent liquid. If the coloration of this fluid is not strange, there is not reason to get alarmed.

There are things that can go wrong with delivery (called whelping), you should read about the process, and be prepared. There's lots of helpful info here:
