First, the third defendant Dr McKinnon is a highly experienced veterinary surgeon able to give instructions as to the reasonableness or otherwise of the expenses at, one would think, relatively short notice. Second, Dr McKinnon, it can be reasonably surmised, is familiar with the treatment of this mare at the clinic at which he practises. The treatment was carried out at the clinic under the supervision of one of his partners, as I so far understand the evidence. The treatment of the mare by Dr Redden, whilst not one of the partners, was also conducted at the clinic. It is fair to assume that Dr McKinnon, in the preparation of this case, is well familiar with the treatment of this horse, both before and after the horse passed his examination. Thirdly, the bills that were delivered to the plaintiff on behalf of the veterinary clinic, which form part of the particulars, have been well-known to Dr McKinnon. True it is that Dr Redden's bills did not come from the clinic but again, his involvement is a matter that does not take Dr McKinnon or his lawyers by surprise.
