I have a bitch that was mated on the 14 th Feb, she only had the one mating due to the long distance between us and the stud dog, they tied for 25 mins, myself and stud dog owner decided we we're happy to settle for that, she had her last litter 20 months ago.
This time is not showing any signs of being in pup, she has had a stringy discharge for the last couple of days. The vets can't do a scan on her until Tuesday.
I'm not holding out much hope for this planned litter!
