I can't wait to read that dog blog link up there! Glad she got a good walk today- mine could use a few more of those too I'm sure. My girl is not usually very food motivated but I was pleasantly surprised when I got her one of those dog puzzles where you put the treat or perhaps in your girls case the food into the different compartments and the dog has to figure out how to get them out. Mental stimulation and fun play- might be just the thing!

This is not the one we have but very similar. Also, perhaps your gal would like a ball better I it had a squeaker in it? Those ones are lilah's favorites- she really just can't get enough of them!
