What (used to ) frustrate me the most with my dog Scout, is when I adopted her at 3 yrs. old, I found out she was not housebroken
It was a LONG battle to get her there: 'accidents' daily at first, then 2 x a week, then once a week, etc.
I could never get her to understand until I actually caught her in the act. I even did the bad 'rub her nose near it' thing when I got to my wits end. I felt that all I did for at least 2 months was clean dog pee AND poop. Went through alot of Natures Miracle!

Well, today she is fabulous in the house, however it took 2-3 months to get her there.

Now, her thing is the getting into the cat box for kitty tootsie-rolls! It's not a good thing, but I don't think it is horrible either- dogs just DO EAT gross things. Fact of life.
I would prefer she did not do it, and I try and watch her, but it still just happens................I just don't let her give me a kiss for awhile!

It is much better than when she was not housebroken. Almost anything is better than that!
