I really don't know why people with little dogs want to take the chance of having their dogs hurt or killed by taking them to these parks.
Maybe I am just too paranoyd and just love my little ones too much but my little yorkies can just be agressive and I would be afraid they would be hurt or killed.
Also, my vet says that it isn't smart because you don't know how healthy or what the other dogs are leaving behind that your dogs could get.
He has also told me NOT to take my dogs into the pet smart, pet co stores.
