The first puppy to check it out was Matilda, she is a bold puppy
I stopped on the way home from work to buy some Veni-Chews for the dogs, and asked if the garden centre did any sort of tunnels for dogs. They said they only ordered them in specially but if I didn't want a big tunnel they did have in stock a rabbit tunnel designed for all sizes of rabbit. So I thought if a big rabbit can get through it perhaps the puppies might find it a fun new toy.
Later they realised that it was so light weight they could move it around themselves and so it was dragged around the garden.
