can dogs tell when your pregnant? im only 5 wks but my bfs dog recently starting laying on my stomach

Yes all animals can

Yes

yes. my cat does it

yes around the time when i didnt know i was pregnant, my dog (may i remind doesnt cuddle with anyone at all or even lay down close to you) would lie right next to me and sleep. she never did that before. where ever i went to lay down or sit she would follow and lie close to me, she stopped doing it once i have acknowledged that i am indeed pregnant but yes dogs are very good at sensing these things. in a matter of fact they are the first ones to know when youre pregnant, sick, cancer or anything else that you need a doctor to confirm.

tumors

Yes they can I haven't taken a test yet but my boyfriends dads dog was cuddling up next to my belly yesterday and my daughter was as well and neither of them ever do that
