Thank you MM-was a bit suprised when friend told me her pup was chipped by the breeder when they were there collecting him....I thought that would be a vet only job!
Not a vet only job but they do have to have passed tests and be licensed to do it; very strict about it too - quite rightly.
Quite possibly the breeder did take the tests; a friend of mine did them because they are a holding kennels for council strays. She recently did an organized day at a local ag' store and chipped nearly 300 dogs!
Interesting question! I have been microchipping my own dogs for over 30 years and I would claim to have been trained by a vet who has now retired and moved to Spain. I'm intending to just do my dogs as usually and send off the registration forms and see what happens. Not intending to chip anyone else's dogs though. My vets use my chips on the ponies. The numbers go in the passports but I don't bother to register them other than that. With the KC and DEFRA involved, it will all be a nonsense anyway!
Pets at Home have people who can microchip their and customer's animals. They do a theory and a practical test but you don't need any other qualifications.
