@Craigh:
Pat - I had an off-topic question since you've got so many older dogs.
I know you're usually against free-feeding, but how do you feel about this with older dogs? If Alex (15 years 6 months) eats too much at a time he usually ends up throwing up. Therefore I feed him two small portions twice a day. However, during the day he gets hungry (it's impossible to put/keep weight on him) and I've been keeping a small bowl of dry food around for him to pick at. He'll usually go by every 3-4 hours and eat a couple bites between meals. Do you see a problem with this? It's so hard to get him to eat and keep his food down that this is the only thing that seems to work longterm.
The way he's been acting the past few months I doubt he'll see another birthday so I try and indulge him any way that I can.
Since you only feeding one dog, I certainly would do whatever works for him… and at his age... if he were mine, I would do exactly like you and indulge him totally
