It's been quite a while since I've had a dog. But my last dog went RELIGIOUSLY 3-4x a day. Once in the AM. Once when we got home, once before bed (11pm). We have a new 4yr old Lab mix. Rescue dog that likely took a lot of crap in her day. She goes at 5am when my wife gets up. She'll go again sometime between noon and 3 when someone takes her for a walk. Some days, she'll go all the way until 5am the next day. Today, she went at 8am. I gotta go walk her around (almost midnight now.) She may not go. That'll be 21 hours. Whaddupwitdat??? SHe drinks some water, but not a ton. I just can't understand this. I'm pretty sure her last owner was an a-hole. She's fairly skitterish and gets very nervous at times. I figger the dude musta beat her into holding it. Or not. Is this normal??? Seems ABnormal to me. Thanks.
