I used to work at an equine vets...what do you need to know about microchips...?
Mildmay are meant to be quite good...Ive attached a link for all the vets in winchester for you...:0) http://www.k9media.net/careservices/services/vets/hants.htm
Is that Riverside Vets, Bishopstoke, Eastleigh? If it is, the stud that stands my filly's sire used to use them but changed to Animed as they were so very expensive. Apparently they started charging by the minute for visits . . . . . Whereabouts do you want a vet?
...normally written down in your passport, or the vet can scan your horse for the number and you can ring defra who will have your details/ or horses.....defra will instruct you or know who you can call to sort the problem....might have to confirm who you are but that about it really...
Mildmay dont deal with horses anymore i used to be with them, they recommended stable close to me when they stoped they are near winchester they are very good here is their website. http://www.horsevet.co.uk/index.php
we have used Riverside in the past, and found to be expensive. Would definately recommend Endells in Salisbury, we used them for years when i still lived at home and we were on the south side of Romsey so there were others that were technically closer...
