lessons to be learnt... if you're are taking your dog abroad, best to make sure that the chip is functional before you go.
if it does not work do not travel. Elsa was in france for 4 months & chip worked fine last time (in feb). when we took her to vet just before travelling home, it could not be read. vet said that it would be ok -DO NOT BELEIVE THAT!. if chip does not read you have to find means of identifying your dog otherwise you have to make your own arrngements to quarantine the dog. if chip can be read once it's removed then defra will allow early realase.if not you could be looking at 6 months. not trying to be a scaremonger, but this is not an isolated case(so we have been told). make arrangements to sort this before you return. ports are very unhelpfull & will not do anything to help. you must do all this yourselves.
anyway happy ending but be warned.
cheers
