I'm no old timer but I've always heard that a gyp will "run out of her pups" if she is over worked or over stressed meaning her body will abort the litter. I don't know.
Yeah, but the definition of "overworked" is extremely different for that gyp and her cousins. I don't say that rudely, lightly or without justification either.
I don't know Tony, but I'm sure she'll be fine and looking forward to hearing about the lil squirts. Best of luck to you bro.
