We adopted a pup from a shelter this weekend. She is 13 weeks old. Her mom was a plott hound/lab mix and the dad is unknown. She was brought into a kill shelter down south with her mom and all 6 of her litter mates around 5 weeeks of age. I know nothing about their history before that. They were in the kill shelter and schedule to be pu down last week. They were rescued by a shelter in NJ that same day. They arrived in NJ at 12 weeks of age. At that point the litter was split in half with 3 going to one foster home and 3 more going to another. She was in the foster home for a week then we adopted her. She was a little hesitant when the foster mom brought her over but out pug helped her come out. By the end of that day she was having fun with us. Now 3 days later she is really out of her shell and doing great. She is definitely not socialized well at all though. She plays with my 7 year old daughter very well, is a little be hesitant of my 2 year old son but she is now starting to lay with him and hang out with him. We've been positively reinforcing that all the time and she is used to him now. But when other people come over, it starts all over again with them. She will stay in the other room and only check them out. She doesn't hide but is hesitant. I know its because she isn't socialized. We've been giving them treats to offer to her and sometimes she takes them and sometimes she doesn't. If some friends stay all day the dog gets used to them and is ok. If its only for a half hour the dog stays out of the room.
Here is what I am wondering. I've read articles that speak of doom if a puppy is not well socialized by the time they are this age and I've read articles that say if we just continue to socialize her and work on it will be ok. I'm assuming I may get the same mix of responses by posting this, but wanted to see what people had to say about it.
Thanks for any input!
