Hi, can anyone give me any advice, my bitch had her pups 5 weeks ago and today she has eaten her own food and then got into the pups playpen and been sick 3 different times, the first time i didnt realise and the pups ate her sick, but it seems to me that she's being sick on purpose to feed the pups, the pups are being weaned, when i went to clean the sick up out of their bed she growled at me.
