I forget what it was called, but when I worked at my vets, we had a policy of giving a dog a free bath if it was boarded for more than three days. If it was staying for less than three days, we sprayed it with a nice smelling spray can. Again, I forget its name but it smelled like baby powder and the owners appreciated it.
There are many, many, many different doggie colognes. Most groomers use a spritz as a finisher. I like the "knock off" designer colognes like Tommy Holedigger, Aramutts, Beautifur, etc. They smell great (not a fan of dogs smelling like fruits and food myself) and leave a nice lasting scent. Oh, and I think the above poster meant "Les Pooch"...I don't like their colognes myself, and they are WAY too expensive for the short time the scent lasts.
