Do the female teats of an English mastiff get smaller after the first pregnancy?

they make shrink back down some, but 99% of them still hang/sag somewhat from my previous experience with them. My females never went back up yet my friends female's did a little...hard to say.

I raise cane corso mastiffs. there teats should not be any smaller then the first time.if teats are small then milk may not be being produced at the rate it should be and the teat will appear small..also please be warned mastiffs are known to get hook worms.and can cause alot of problems i just lost 7 pups to hook worm.mother appears normal but the larva is passed threw milk and blood to the pups and the pups will die in 2 weeks. Matiffs are also known for parvo.you should have the dog checked at a vet..my pups were fine big strong but with in 2 weeks they all died within 12 hours of each other.And its very painfull to pups ..heed the warnings with mastiffs..
