Questionhow do you no that your jack russel is pregnant???
AnswerZoe
You can either wait 4 weeks until you can feel puppies inside or
you can go to the veterinarian and they can confirm it for you -
If it's early in the pregnancy they can do a blood test, if it's later, the vet will be able to palpitate (feel) or listen to hear if there are puppies inside.
The sooner you know, the better for the puppies - and for your dog, she will need extra
attention, food, care, veterinary attention and lots of love.
Good luck
