I don't think Dixie is the smartest dog ever. And she definitely has A.D.D. Potty training is a case-in-point. She knows what I mean when I say, "Do you need to go potty?" and she will get excited when she does. So I take her out. But she immediately gets distracted by all the fun things outside--leaves and dirt to chew on as far as the eye can see! So she puts as many of these things in her mouth as possible and runs about having a great time in the 115 degree heat. I continually remind her to go potty but she has selective hearing at this point and 5-10 minutes later I make her go inside, giving up. Not 2 minutes later I'm cleaning up her accidents inside! So this can get frustrating. But sometimes we do have success outside. Especially in the morning when we've had to hold it all night long. Hopefully the A.D.D. will diminish with age. We'll see...
