This is anecdotal to just my dog but she seems to really like it. Once I start petting her, it’s only a matter of time before she rolls into her back. If she’s next to me in bed and I stop petting her belly, she does a little squirm/wiggle until I start again, it’s very cute until I mistakenly start petting her too early I the morning and then I’m not allowed to go back to sleep.
