Hi, Yet another question! My pug is 5 weeks pregnant. She seems to be really heat intolerant or just generally panting a lot. At only 5 weeks and scanned to see around 5 pups she is clearly showing and very tight, she looks so uncomfortable already. Is the panting normal? I am not over feeding her she is on normal rations of dry food but does appear large and uncomfortable. Just worried for her for the next 4 weeks!
