Nice mutt, but were you not temped by a friendly whippet like STMO's mutt.
I'd have
loved a greyhound, whippet, lurcher.. but they have a habit of chasing anything that moves quickly and one cat tends to move quite quickly! (T'other one is 9 so moves a bit more slowly..)
Also Louise thinks they're ugly on account of how skinny they are
As for the chewing, get a piece of thick rope
Much better then so called indestructible balls.
Also great for swinging him around on when out playing
A friend of ours bought a "rope with a ball" over .. the ball lasted five seconds but the rope is still going strong! He much prefers chewing something "squishy" though.
Kong Extreme toys (look like giant black butt plugs..) work well too as we can stuff those with treats - another tip we had was stuff them with treats, seal the end with peanut butter then freeze them.. takes a dog hours to work his way in to the treats
I don't know if your getting him insured but might be worth looking into
Aye - all ours are insured.. He costs a lot more than the cats, though, so you could argue that it's a mugs game! ~£25/mo for "good" cover (i.e. pays out for the lifetime of a condition rather than just once, so covers things he might need for the rest of his life) and that's a good £300 a year; a few years of that and you'd be better off not paying.
Though it does give us a big chunk of public liability cover, just in case he does something to someone else/elses dog/car/door/etc!
