He is such a cute little fella!
Yep! Mine have always done that. A funny thing Kacee does. When we are walking in the grass, we are moving right along at a brisk pace. Suddenly and without warning I will feel resistance on the leash and I'll stop and look at her and she will be a froggy doggy flat on the grass with her hind legs straight out behind her! She does that when she comes across something she wants to stop and check out if I am not paying attention.
