Good to hear there is no medical issues.
This reminds me of my brothers dog! When ever he was left in care of the teenage boys they would ignore him. To the point that if he had to go he went in search of them and almost always found them in their room playing video games. Neither one wanted to get off their lazy butt to put the dogs out so " he peed and pood on their beds" Ya think that after once or twice they would get the hint.... but nope!
Same thing with my son... in the am the rule is first one up put the dogs out! Well when he gets up he heads straight for the play station game. So, there have been times when they have literally pooped "Right Beside Him" as he sat there on the floor totally inbound in the games.
I guess they showed them....!!
Clean up in isle 9......
Solved that problem real quick.. Now my son loosed play station Privileges if he doesn't let the dogs out in the morning.
