If they are the same as I saw in the local Red Cross the other day, they are big enough for a jack Russell!
- The one they had must be ancient as parts of the plastic had come away and the metal underneath had gone rusty - that does happen slowly over time but as long as they aren't bashed around they should last forever. Mine belongs to the branch and is about 3 years old - it has 2 tiny patches of rust but probably due to the fact that I put it in the garden and forgot about it. I just brought it in to clean it up for Lazarus tomorrow
Might be worth asking your vet as Sharon gets ours through one of our vets and pays the same price but no delivery charge.
