My two year old CoJack girl sleeps next to me. When she is asleep she grunts like she is talking. Is that a usual trait?
YES. Our lab even "runs" in his sleep. He usually sleeps on his side, but all 4 legs are going 90 miles an hour. Often he will also bark or growl in his sleep. Our shepherd also does, but not as much as the lab.
I would love to know what they are dreaming of...
This sounds like common dream behavior, though if you're worried about her air passage or sleep apnea (especially if she's one of the pug-nose kind of dogs) then you can take her to a vet.
We have a cat that snores so loud! I've heard dogs snore, too
Dogs dream, too. That could be a cause of the grunting
