Dogs during pregnancy.

So I’m only 3 1/2 months pregnant, I have two little fur babies & both are very well trained with toileting. However, this last week and a half ONE of them has peed on our bed 3 times!! Each time in a different spot, I’ve not caught them in action so I’m really not sure which one is doing it, but I’m guessing it would be the same one each time!

Of course I change the whole bed covers & give them a deep wash & clean the mattress thoroughly, so it’s not as if they can still smell the old urine.

I guess what I wanted to know was, has anyone’s else’s dogs or pets exhibited this same behaviour? What did you do to help eliminate the problem?
