Gone off in a huff

It's a large greyhound, who have I have met through a Glass door. I have had some hypnotherapy before but clearly it doesn't seem to have worked.
It just fills me with dread for days before.
Meeting half way is not an option I'm afraid, maybe biting the bullet is the way to go, with a stiff drink

Go! They are compromising.

This is a good example of give and take - you need to go minxie or find somewhere else you can all meet up. I think your DH needs some TLC when he comes back.

Couldn't the dog go into the kitchen or something?

If you live 2 hours apart why not find somewhere in the middle where you can spend time together? A small town, a beauty spot, NT property, nice restaurant, anything. It would only be an hour away and you could have a nice time together and heal the breach. That's important, before it blows up out of all proportion.
What kind of dog is it? A Rottweiler? APoodle?

Go! If they are prepared to put the dog in a cage they are meeting you halfway so you should compromise too especially if your Dh does a lot for your dad.

Can you get treatment for it?
