Thanks. I totally agree about it being a procedure to use with care. I'm thinking more use the technique, or have a dead lamb type decision.Yes I bought a few specially and have them strapped on the side of the glucose pot in the meds cupboard.
And note the temperature.
IMO this is not a procedure to undertake lightly - I don't like the fact that the vet above seems to be using a "healthy" lamb as far as I can see.
The best thing we ever learned was that heat is no good if it creates drafts through air movement.
Might have to get someone experienced to show me properly.
