I agree with everybody - esp Alan
Borzoi - are you MAD????? They have a brain the size of a pea and that's being generous!!!!
Sorry to any borzoi owners out there
Two DH is soo much easier than one! Each breed does seem to have their own special sort of playing. Not that they can't play with different breeds but it's never quite the same as same breed.
The only thing I would say is that it is nice to have your first one and get it trained and loyal to you at a young age before you start your 'pack'. It makes things easier - so from that point of view I wouldn't rush in to another if you don't feel quite ready yet.
And if you decide again the cost of a another deerhound there are heaps of greyhounds and lurchers desperate for a nice home and won't mind if your garden isn't huge it's better than a kennel!
Sorry,

playing devils advocate now
