The Penn Vet Working Dog Center (www.vet.upenn.edu/wdc) relies on fosters for socialization of the puppies in training when they are not in school. These dogs are in motion all of the time! Most weekends are for kicking back and relaxing, but sometimes there is a bit of homework, especially if the foster happens to be Dr. Otto . . . Join Blitz (and a cameo of Dolce) for a fun filled weekend.
