House training issue resolved! She is weeing every 20 mins so i have put down puppy training mats and she is using them when caught short. Mind she did disgrace me in the pet shop the other day. Stood in a queue at the till and she has to wee, so she did! A non absorbent concrete floor! All i could say was, i am so sorry she is pregnant!!!! Lame but valid excuse i thought.
The vet wouldnt commit to numbers from the scan but said he saw around 5 so may be more. She is 5 weeks and very big already!
