I have no idea when my girl was in heat but I noticed around 2 weeks ago she looked a little bigger, we had just lost our male on 10/3 so we were really hoping for puppies to keep his bloodline going, & that is the only way my hubby will let have another pup. The diagnosed false by palpating her, we didn't have money to do ultrasounds or xrays so I just wanted to know how often vets could be wrong in the diagnosis by palpating? Thank you for any help.
