I can't recommend anything specific, but Amazon has quite a large selection of chew-proof dog leads of various lengths and materials.
A possible alternative would be to spray all the leads with an anti-chew training spray. It is safe for dogs, and can be used on fabrics among other things. It tastes disgusting! Kitty was quite a chewer, and this certainly stopped her! It does need refreshing every so often though. Johnsons Veterinary has a very good anti-chewing training spray and this is available from Amazon too. A lot of pet shops also stock it.
Good luck!
Many thanks. Will certainly try the anti-chew spray and also will have a look at some of the various options for leads - currently am thinking of much shorter leads attached to their new posh Greyhound Trust harnesses which have just been delivered and which they seem to like.
Experimenting with anti-chew spray on the webbing leads and a shorter chain lead - Rita was not amused when she reached down and took a mouthful of it, gave me one of those greyhound looks, but it's definitely chew-proof! Many thanks for suggestions.
