My girl is 7 weeks pregnent but yesterday and today she is sicking her food back up, she had a litter 2 years ago but never did this, i phoned my vet and she said not much to worry about but i am, i have booked a appointment for tomorrow but can anyone tell me if they have had a bitch do this..........

Yes :-D The stomach can't hold as much as it could before she was pregnant but her eyes will still want her food ;-) It isn't anything to worry about so long as she is fine in herself.

try feeding little and often so she has chance to digest before eating again

Agree with newfienook - try 4 or 5 small meals a day.  As long as she is getting the nourishment she needs, it really doesn't matter how you split up the quantity.

Hi Thanks to everyone for ur advise, i have been giving her 3 meals (small) but i am going to try to give smaller 5 times a day. Thanks again.
