I have three dogs, and all are a bit different:
Maguire (13yo Yellow Lab mix) can’t go more than 4 hours without going outside, or doing business. Lots of wee-wee pads, and getting up at 3 am. Getting old sucks!
Maggie (5yo rescued Chiweenie). She, as others have said, thinks that anyone on the toilet needs to be petting her whilst they sit upon the throne. She comes running at top speed whenever someone heads to the bathrrom, and will claw at the door until you let her in if you open the toilet lid. Turn on the bath, and she runs and hides! She is also insanely jealous of Rocco, and will insist on sitting on your lap whenever he does; accordingly, poor Rocco ends up on your chest, pushed out of the lap (which is quite endearing, I might add).
Rocco (2 yo rescued Chihuahua)… well, see, he ends up right on your chest, all evening long. That’s no problem… but…
Very S, VERY D. Sound asleep, snoring loudly, and passing gas that will curl your hair, inches below your face, on your chest, because Maggie (the bitch!) won’t let him ever sit on Daddy’s lap.
To top it off, he never farts when they are sitting on my wife. Just me. Must be love.
