Hi--I just discovered this website a few minutes ago. I was searching on Google for dog breeds who have webbed paws. I, like you, got a puppy from an animal shelter. I have had a few dogs in my lifetime; but this puppy that I have now is the first one that I have ever seen with webbed paws!!! I am sorry that I cannot provide a picture of my 5-month-old puppy at this time; but she is a short-hair and she's tan and white and very, very cute---just like your puppy! The animal shelter says my puppy is part Australian Shepherd and part Mountain Cur. She's a working dog species. She loves to sniff and she loves to chase things that move. She has been in water puddles in my yard. She doesn't mind much being in a bathtub. I couldn't do that with my other dogs that I have had! When summer comes, it will be interesting to see how my puppy, whose name is Bella, will take to the swimming pool that I have for my 3 grandkids. Your puppy resembles my puppy as far as the short hair and markings go---even if yours is black and white and mine is tan and white. My puppy has a slimmer build compared to your puppy. Enjoy your puppy---he's a cutie!
