The only anti-chew spray that really works for determined cribbers! The only criticism is that like a lot of the Eqyss products the trigger spray is a bit flimsy and can leak, so it needs to be kept upright in a safe place or you can easily waste what is an expensive product!

Have not had time to really assess this product. But seems to be doing the trick.

Bought this on recommendation from a friend as one of our ponies has chewed my horse's tail! Hoping this will put a stop to it. Have only been using for a week, but so far so good.

Effective and stopped the problem of wood being chewed.......straight away! As instructions avoid breathing it in and be careful when spraying as pretty potent! Super quick delivery as always.

Best product for horses that chew. Nothing compares. Just don't inhale the fumes after spraying it. Will be coughing and sneezing for ages!!!

Excellent product - I used this for a horse which insisted on chewing his friends' rugs and for another horse which had a penchant for chewing tails! Great solution!

suberb product!!! This is the only anti chew product that has ever worked for my horses and especially my dog (who will stop at nothing to destroy his bedding). Mcnasty is easy to spray on and lasts. I usually re-spray every week for my dogs bed. I can not be without this product. Mcnasty is non toxic and one lick does the trick. Thankyou for having it. jill
