My in-laws had bought a puppy, of the breed Staffordshire Bull Terrier, to replace an elderly Staffordshire that died some 6 months before. They never had a puppy before and had little dog training experience. The dog, now about 6 months old, has some problematic behaviours which are largely because the my in-laws whole household (3 adults and a child) haven't dealt with the behaviour in the right way from a young age. I think they liked the idea of having a puppy, but didn't do the research before they got her and failed to apply consistent training.
I'm no dog training guru myself but I have adopted a problem dog from the dog's home in the past which had behavioural issues which I had to overcome and I have assisted in training dogs when I was a child.
My in-laws have reached the point that they are seriously considering giving up the dog for to its behaviour.
The dog's issues I believe are centered around play aggression that they have inadvertently encouraged by rewarding the behaviour with attention. This had led to some situations with my own children and the 11 year old becoming scared of the dog, she bites and jumps at their faces. Unfortunately this behaviour is then re-enforced through her getting attention, or being lured away with dog treats. It hasn't yet turned into any dominance type aggression, it is mostly just over exuberant play at this stage.
I feel like the issues are easily solved so long as disciplined and consistent dog training practices are employed, they are going on holiday for two weeks soon and I'm considering looking after the dog for that time to try and make some improvement with training while they are away, but I have some worries as follows.
I have a dog, mentioned above, he is now a docile 8 year old, Collie Beagle cross. The staffy puppy would be coming into our house for two weeks and while the two dogs have met on a few occasions, it could cause tension between the two dogs if they are living in the same house.
A lot of the puppies play aggression comes out when my young (2 and 5 year) kids are around, so bringing her into our house would place her into that trigger environment every day.
I'm used to dog training and being the assertive alpha male, if I was able to make an improvement after two weeks, I'm worried that her then going back to her home may just confuse her, make her behaviour worse and she may just instantly revert to her old ways once under the charge of the in-laws again.
In short, I have one question. Is adopting her for two weeks and trying to 'fix' her behaviour in that period a terrible idea and could it result in more behavioural issues? Or is it worth while to prevent them giving up the dog permanently?
