If its barbaric, then why do the RSPCA it to cats? Oh yes, silly me. I forgot, its because they don't have a clue about animal welfare!!!!!!!!!!!
Seriously though, they came to a friends farm which they had just purchased, complete with about 30 odd feral cats, and cage trapped them, neutered them & returned them again. The only way they could differentiate the neutered ones from the entire ones was by notching their ears.
We do it to sheep too, and have never had an ill effect.........done several thousand of them in fact!
I have never come across it done to dogs though.
