Ideal for dogs of all sizes! For both large & little ones that love to chew, nibble, gnaw & play, sisal is the perfect play treat, because being a natural plant fibre, if they ingest any of it, it will quickly break down into tiny pieces in their stomachs & so never cause intestinal blockages, which can happen with cotton rope & other toys. Plus, the added bonus of the rough texture of sisal is that it is an excellent dental cleaner when chewed, a bit like dental floss for pets! Also, being entirely natural plant material, if lost in the woods or on the beach, sisal will biodegrade quickly & harmlessly, so protecting the environment :) These knotted rope toys are each individually handmade by us. You can purchase a single knotted rope, or a set of three. They measure approximately 50cm long, & are ideal for all dogs who like to chew, tug & throw their toys. As they are handmade, sizes are approximate & may vary slightly between each one. Our sisal is sourced directly from a UK supplier, & all of our products are packaged in eco-friendly packaging which is recyclable, biodegradable & compostable where possible.
