Housebroken dog peeing in other people's houses
We are visiting our relatives for Thanksgiving, and brought Barkley (year old lab mix) along... He had an 8 hour car ride to get her and refused to go to the bathroom the whole day. (We let him out 4 times at rest stops in an 8 hour period, and gave him water) Is this normal?
Additionally, he has peed twice and pooped once in our family's home... he has never done that before at home except for the time he peed directly in front of a visiting friend. (See previous post). Is this a case of confusion?
Lastly, I have a general question... whenever Barkley eats something that tickles his throat or gets stuck, i.e. a piece of fuzz or thread off the floor or whatnot, he begins to lick the carpet if we are inside or eat grass if we are outside. This can go on for several hours! One evening, he ate something when I wasn't looking (no idea what it was), then proceeded to lick the carpet from 8-10 pm (we couldn't get him to stop!), then eat grass for almost the whole time on his evening walk at 10:00 before bed. We put him in the crate and he seemed to settle down and go to sleep, but I awoke at 3 am to the sounds of him eating his blanket! I got up in the morning and discovered he'd eaten 4-5 large holes in it! Needless to say, it was not pretty over the next few days... he had bowel movements and there would be pieces of blanket in his poop, and at one point, he pooped out JUST a piece of blanket! Pretty gross.
Is this licking the carpet continuously normal? Or is he fixated? It's very odd. Also, why the heck would he want to eat his blanket?
