I typically take Nimbus to the dog park on a regular basis. When we're there, she will ALWAYS poop after running around for a short while. I reckon the physical activity encourages her to go. But when she's on leash, either on a walk or just out for a potty break, she will only poop if she REALLY has to go, and she'll spend at least ten minutes sniffing about and running back and forth at the end of her leash before she does it. This week we haven't really been to the park due to a lovely April snowstorm (Winter just had to have one last hurrah I guess) and I've only been getting her to poo every other day. She's gone as long as two and a half days without pooping before. It's not that she doesn't have to go, as if I brought her to the park every day, she'd go without issue, and she doesn't ever seem distressed, I'm just wondering what I can do to encourage her to go when we're not at the park, or if this is something I should worry about. I don't have a fenced yard, so I have to take her out on leash. I've tried taking her out on a long line, but even then, she still won't go unless I play with her first and get her to run around for 15-20 minutes.
