Ok, fair enough – I can see some plusses to it but, I don’t think a lot of owners would be happy with a pup being injected in the ear, plus you have the accepted standard of between the shoulder blades for scanning now. I also refuse to accept that migration is any more than an uncommon inconvenience which very rarely requires intervention in routine use.
I don’t follow your last comment though re tail docking – are you suggesting that’s a “lost income” now it’s been banned or that vets have to do it in the rare cases it’s allowed (a whole different argument!). Either way, I have only ever met a handful of vets who would even consider docking tails, before or after the “ban”. But then I guess we’re straying OT again.
