My female is pregnant. The last lock up with the mail was a 71 days ago. She has a large stance for her breed. Previous to getting pregnant she weighed 84 pounds she is at 91 pounds as of right now. When should I take her to a vet to get a follow up? She’s acting healthy she’s been going on and off feed him once a day for the last weeks. She’s producing milk, she’s carrying around her Stuffed animals, she’s been sleeping more, she’s been dreaming more but overall she’s healthy. Minus running around the backyard all day. I’ve extended her walk by 2 miles so she walks approximately 3 miles a day on top of the normal fetching in normal activity she gets.
