Have seen this toy on the internet and am very impressed - its a highly researched dog toy with extra tough stitching, chemical free fabric and five squeakers in different parts of the body.  it has passed all sorts of tests in the US and I want to buy one each for M&B.  Does anyone know any UK retailers who stock this product?

If you look at their stockists some of those have UK companies such as Orvis.  I don't know which toys are specifically Hugglehounds but you'll probably recognise them.

Alternatively many US companies are very keen to ship overseas and US postal prices are much lower than we are used to.  I've ordered collars from America and often paid less than UK prices, even with postage.  Try eBay too but ask for combined delivery rates for two toys.
