Is my 30-day pregnant dog's weight gain due to puppy size yet?

Updated On September 23rd, 2025

Pet's info: Dog | Chihuahua (Long Coat) | Female | unspayed | 2 years and 1 month old | 4 lbs

Are the puppies big enough to make a difference to her weight? She’s 30 days pregnant and she seems heavier when I carry her and pick her up but I don’t know if I’m imagining it do you think the puppies are big enough to actually make a difference to her weight?

She technically is just now going into her 2nd trimester, so the puppies are still quite small at this stage. That is likely why she sort of feels heavy for now. I would recommend actually weighing her to get an accurate assessment of her weight gain during this time. Thanks for visiting Petco Pet Education Center, formerly Petcoach. Take care. : )
