Sorry if this is long!
DH's best friend is in a desperately sad situation with a child who has a long term illness and is regularly hospitalised.
They have a dog which "we" (I) have looked after before. I love dogs and the dog is really well behaved when owner is around. As soon as owner left the dog was trying to hump and grab my children and I ended up locking it in the kitchen to keep the kids safe in case its behaviour escalated. There was no aggression but I was worried the dog was overstimulated and could nip or escalate. It caused quite a bit of damage to the kitchen once locked in there so wasn't ideal.
Once owner came back it was instantly well behaved again. Think they train it very Cesar milan style with dominance etc so it clearly just got "I can take the piss" vibes from me.
DH now wants us to have the dog again, overnight this time. I'm massively uncomfortable with this but DH says it'll be easier this time because he'll be here and can control the dogs and keep it away from the kids if necessary. He's giving me a massive guilt trip because of the awful situation his friend is in, and maybe he's right and I need to be more selfless. I also have anxiety so tend to see danger in every situation so I thought it would be helpful to ask some dog minded people for advice.
Wwyd?
