Hi my dog is 31 days pregnant and I’m wandering what happens in her pregnancy at this stage? Do the fetuses start to look more like puppies? What happens today?

Hello. You might be feeling the beginning of some mammary swelling, but it is way too earl to feel any puppies. Each fetus would be smaller than a marble at this point. You can follow her pregnancy doing an abdominal ultrasound in another week or so, or an x-ray after 42 days. In a small breed dog, it is not a bad idea to know how many puppies Trixie will have so that if she runs into problems, you will know when to act. Hopefully, she will have a stress free pregnancy & she has a beautiful litter. Thanks for contacting Petco Pet Education Center, formerly Petcoach.
