I could see my bitch was pregnant this time by 4 1/2 weeks (had her checked for pregnancy a week earlier), and by 5 weeks she had a very obvious pregnancy belly. She looked huge and went on to have 7 pups, just an average number for the breed, whereas shw looked like she might have more. for ehr first litter she looked quite big, yet only had 4.
Think about it 9 weeks for bitches 9 months for humans. In many women you can see they are pregnant at 4 1/2 to 5 months, in others you can't especialy if they are big girls or wear lots of loose clothing.
On the other hand at 5 weeks pregnanct I was sure that one of my girls was either not in whelp or was carrying a small litter. she showed no signs of being pregnant and was very slim. she went on to have 9 puppies.
There are women who never know they are pregnant until they ae in labour and even the doctors se no signs until this, and many a bit6ch ahs confounded Vet and owner in this way.
