I tried giving away a dog in trade, but we get these error. 
I tried with four people, they all told me that they have space.   

You cannot accept this trade currently as the other player is unable to accept this quantity of Dogs. Either remove Dogs or ask the other player to make space for additional Dogs.

Hey Cazar,

Apologies for that, a fix is going out now.

18:24:23 - You can't accept this trade as the other player cannot accept this number of Dogs

Hey Cazar,

I'm just deploying an additional fix now, can you please test again from 11:15 onwards and see how you get on?

Thanks for working on this Fix Diablo.

looking forward to when I can accept a Rare fleabag from my Capo!

Im getting same bug

Fixed. Thanks for fixing

Glad to hear it's fixed, I'll close the ticket
