I've had to travel a few times, it is always hard. Once I found someone to check in on Auggie. The other times that person had moved away and I didn't trust anyone else.

I have left Auggie over a weekend. I have him plenty of food, and I filled up several water supplies. He usually has one water bowl and one hanging water bottle. I cleaned out his regular water RIGHT before leaving and I filled the water bottle, AND put another big water bottle up. He didn't go through much of the water, but I did want to make sure he had CLEAN water.

This worked fine, he sure missed me by the time I got back, but there were no problems.

Of course if you can find anyone to check in on them once or twice that would be best, but for a couple days they can do pretty well on their own.
