You have worked so hard for Archie.
With my Millie, myself and another lady having been bitten by a muzzled dog 5days ago, i can only imagine what you are going through and the worry that your daughter must feel each time Archie is near... I've been avoiding other dogs in the park...
If you muzzle Archie, please use a basket type and dont be worried that its too tight! That way he cant bite forwards, which is what happened with the dog that attacked M before the cloth muzzle came off without being undone... That enabled the second more deadly attack to take place....
Is it fair to your daughter to risk an attack, even if Archie has a muzzle on?
Surely by rehoming him, it will ease your family's stress and Archie's too.
Dont forget someone on here suggested that he might be offered to the services: that way he will be fully occupied for much of the day.
As an alternative to Last Chance have you also tried contacting Wallace Kennels in Essex? 01277 821032. They would need a full history which I'm sure you would give....

You have tried your best with lots of love and dedication, but doesnt there come a time when family has to come first...
Tbh, if they will take him, I think that is the best option. Personally I would do it asap
. Can't help but agree with Joules..
Good Luck!
PS Millie is recovering well!
