Dog not eating (Update, problem solved)

***Update: We put the canned food into Max's dish, and he gobbled it up. Problem solved! I'm going to make sure that we give him a walk tonight and/or tomorrow, since he loves getting walked and it's been awhile. Thanks for the suggestions!***

This is kinda random, but does anyone who sees this know what's up when a dog just stops eating? It's Max, our sweet mutt. We've had him for almost 2 years and he's just the nicest animal ever. He'll pick at his food, but he still goes nuts when we're cooking or when we're feeding Andrew so it's not like he won't eat anything. Just to clarify, he barely gets any scraps, just a small portion of what Andrew throws off his tray and what falls off the counter when we're cooking. Toby gets most of that food, and it's not much to begin with. Max is drinking his water, at least I think he is since it's outside, and he has no sign of any gastrointestinal problems. He started losing weight when they were in the kennel for a week, but they said he was eating his food. Although, since we asked that both dogs be boarded together, I wonder if Toby ate Max's food. Toby, the cocker spaniel, is the dominant one between the two. I've started feeding Max behind a gate, to keep Toby away from his food, but that didn't help. I even poured maple syrup in Max's bowl, but that barely helped. I called the vet and she said to bring in Max in two days if things don't improve. She said to mix in some canned food in the meantime. I really hope that Max doesn't have a serious problem. We just can't spend the money for, say chemo or whatever major intervention they do for dogs. At the same time, I'd hate to lose him. I don't want to be put in a position to have to choose between keeping this amazing animal alive and paying for another adoption. I know what I would choose, but that doesn't make it any easier. Please pray that it's just a result of stress and that Max recovers in the next couple days.

However, as one problem crops up, another got taken care of. We spent all day yesterday taking care of the pest control problem. We got a pest inspection Saturday and did every single thing they suggested. We could have paid them $250 to do it, but we got the supplies for $50 and did it ourselves. After I emptied and scrubbed all the cabinets and the pantry, I decided to take advantage of the hassle by painting them this week. The house came with the wrong kind of paint in the kitchen, and it looks horrible. I've been meaning to repaint it since we moved in, but haven't been motivated enough to take care of it until now. While it was a long weekend, at least there will be some long-term home improvements as a result.
