I remember him! Well, Gabriel Hagard, anyhow, maybe the same fellow? Here's the text about him from Animal Hospital.

Gabriel Hagard
Gabriel has wanted to be a vet for as long as he can remember. He has been at Harmsworth for eight years. His first day at work was also the first day he was filmed for Animal Hospital and he's been a regular ever since.

Life as a Harmsworth vet is unpredictable. "When I arrive at work in the morning I have no idea what will be waiting for me! There is such a great atmosphere here and we all have a lot of fun working as a team." As well as examining pets in the clinic, Gabriel keeps an eye on what's happening in the wards and operates in one of the hospital's two theatres.

Gabe is the very devoted owner of three cats and a rescue dog called Spike who was brought into Harmsworth as a stray. Spike was very thin and weak when he arrived at Harmsworth, but now he is in tip-top condition and bounds around with an unbelievable amount of energy - something the team in the production office can vouch for!
