Totally understand. My mom is the same way. She likes dogs and animals; she's just not a dog lover. Dad's far more into animals than she is, but even he kinda looks at me like I'm crazy about the dogs.
Like during our Easter Egg hunt at my parent's house. We brought the dogs along also, this isn't unusual the dogs go pretty much on all family outings. But then I was taking pictures of the kids and when the kids were done I was taking some of the dog playing. Dad was like, "Of course, she's taking pictures of the dogs instead of the kids." This was totally untrue, I'd already gone through 2 rolls of film of the kids finding easter eggs, (also hubby had the video camera set up, as well as taking some pics with the digital camera)Also I was taking these pictures of the pups while my children were headed in to the house to go through their 'booty'. Anyway, I can relate. . . Just have fun, and don't pay attention to the critisim. There are much worse interests than your dogs.
