Another dog to stay - finding it really hard to deal with HELP!

[DustyBustle]

A plea for help/advice and a bit of a rant actually,

He's a 3 year old boxer and we've looked after him before as a youngster (9months) - but he's so unruly! We though last time he was hard work because he was young and we weren't used to the breed - but OMG he's such hard work and really upsetting our lovely collie.

He pulls constantly on the lead - I've tried the stop start thing but it's relentless and my poor dog is not getting a good satisfying walk at all. And I'm being pulled along all the way, he just doesn't seem to be getting it!

When I let them off for a run he just jumps on and mouths my dog, who just then glues himself to my side.

He's jumping up at visitors, scratching doors, - howling when left for a millisecond, jumping all over the furniture.

You know like when you adore your own children but can't stand other people's? That's me right now.

I know it's not possible to properly train him in the week we have him but he's just not responding to anything!

You could try correcting the behaviour but not sure that is going to help in a week with all the issues you have. I would certainly not look after him again if it is upsetting your dog.

Take them out seperately.

I think you need to walk them separately to be fair to both dogs.
Could you use a stairgate in the house to give each a bit of space and keep bouncy dog from rushing at visitors etc? It's easier for the dog to settle behind a stairgate than a closed door - can still see and hear what is going on, ca be rewarded for nice quite behaviour etc
Realistically you are not going to change much in a week, but you should be able to make things a bit easier.
