Yup I think most of our dogs need to find the right spot and are very selective when they go potty.
Make certain that if you have long grass or long shrubbery nearby that if he/she goes and does her business there that you check for ticks if you have ticks in your area every day!!
My girl got a paralysis tick on her when she was 13 years old at the time and she was very close to death. It only took a day with the tick on her before she started dragging her hind legs (they were paralyzed) and getting VERY sick. We were very fortunate the vet was able to save her and she was able to recover her leg functions completely.
We didn't keep our girl outside she was an indoor dog, we live in a suburban area and never thought that could have happened to us but it did.
