My son adopted a 2 yr old pitbull last yr.Due to relocating my mother now has the dog.I was unable to take her as I have two other dogs.Not sure how long we will have the dog before my son returns but in the meantime I'm worried about socialization skills.My mother is 70 and very attached to the dog but she is not strong enough to give the dog the exercise it needs.I walk her as much as I can but due to my schedule its very difficult.My son always had her around other dogs and people but my mother is afraid if she acts agressive she will not be able to restrain her.Lately she's been acting very aggressive if she sees other dogs.We want her to be able to interact with other dogs.Are there training programs around (St lucie County) that teach socialization skills.I've had her around my 5 mo. old lab and she is great but when it comes to toys she is very possessive.I keep her within 2 ft. of me at all times.We feel that she needs interaction with other dogs and people but aren't quite sure how to go about it.Any suggestions or comments would be much appreciated.
