Hi LabLover! Wow...Did your parents give you the OK??? I know that you just adore Sadie May and are just beginning to get into agility and other fun games with her. That alone takes up a lot of time, attention and dedication. Puppy's do take up ALL of your attention and a lot of your time! Will you be responsible for the puppy's care or will it be a "group effort?" Considering that you say that Sadie has a few issues with jealousy, dominance, (?) and such, maybe you can take her to a class for some re-enforcement in socialization with other dogs? Or inviting other dogs over for play time, going to doggie parks, etc. I think it would be better, if you decide to get a puppy, to get her feeling more comfortable around other dogs, AND puppies, and especially seeing YOU talk to, pet and play with other dogs. A lot of dog classes will work with you on socializing etc. I have a friend with a 4 year old dog that she took to a puppy class, just to get her accustomed to enjoying being around puppies and children, before getting another puppy. Well, more info!!!! Whatever you decide, tell Sadie I think she's #1!!!
