"I have to say that until it happened to my dog, I never knew it could happen. 2 puppies, one sac with umbilical cord going from puppy to puppy and a 3rd cord going to mom. It looked like a Y or T. I just buried the babies as they did not survive. I could seal them up and send them to you if you wanted to see this yourself. Shocked the heck out of me - a seasoned and experienced breeder. My vet says this does happen just not very often."Anonymous 4-25-2015
"My dog had a litter of 15 on 11/12/15. She had a set of twins at 7:57am. 2 pups, one male on female, come out the same sac attached to the same placenta. So yes, it is possible! I couldn't get a picture as the mother quickly tended to them. The female twin is very tiny about a third her twin brothers size but she is doing well and is definitely a fighter."Samantha S 11-15-2015
"My dog just had identical twin girls, she had a couple of hours after birth of first pup, then delivery of second was much more of a struggle. When it finally came out she got straight in and began cleaning the sack away so I never got a good look immediately, but the slimy blob definitely seemed bigger than the first. When I lifted her leg to make sure she was getting the membrane off it's face, I realised it was actually 2 pups in the same sack, one laying on top of the other, both head first. They were identical, both cream, both females and even both exactly the same weight, at 174g each, whereas the first pup only weighed 145g also a female, but pure white".Mandy 12- 9- 2015
"Add me to your list! I had three sets where two pups attached to each other via a Y umbilical cord in one litter [of Alaskan Malamutes]. I have never seen that before or since. I was told by Cornell that it is a very rare occurrence and was due to the uterine environment and that I most likely will never see it again." 6-9-2016
The original post is below:
Can dogs be identical twins, meaning two animals developed from the same fertilized egg, having the same genetic material and delivered in a single amniotic sac? The answer is somewhere between not likely and probably never.
|That's just your reflection Bud, not your twin.|
They can also be half sibs meaning they have the same mom, but different dads.
|Identical twinning in cats is|
|Are these Aussie twin pups? Not likely.|
|Twin cows aren't unusual|
|Baby armadillos are identical quadruplets.|
|Just a band of brothers (and sisters)|
