Hi all
Am new to the forum and would appreciate any advice.

My bitch has 4 3-day-old pups, all bitches. There were no complications at whelping and all pups are warm, plump and either suckling or sleeping and gaining weight. Hardly any crying. Mum is generally relaxed (she is an excitable bitch at the best of times!), eating well and taken to motherhood very well. She's doing a grand job.
However, the smallest (and last born) has a small amount of milk coming through her nose after suckling. I have read many threads (this forum is excellent and a mine of info!) and understand this may be caused by a cleft palate. We can't see anything obvious but if so I imagine it would be a very small hole as it is not much milk? Puppy is not too keen on an oral examination and that sets mum off fretting as well. Many members have said such pups should be pts but I am very reluctant to do this as she is gaining weight and seems fine in all other respects. We plan to keep one so she would be the natural choice. My questions are, should I just wait and see how things develop or should our vet see her? Will it achieve anything at this point? Longer term, if she does have a small hole can it be 'repaired'? Will it set her back in other ways?
Thanks for any advice
Jon
