I have a 13 yo maltese x shihtzu dog which i've had since it was a puppy. I can't get over the fact that she is now 13yo and may not have many more years left in her. She is truly one of the family and my very first dog, so she is very special to me.

All she does now is sleep most of the day and is not very interested in playing with our other dog who is also a 10yo maltese x shihtzu. Our older dog has arthritis in her back leg so i can understand why she is very sedentary.

She loves barking at other dogs and people who go by our house, but otherwise is very quiet and likes to take it easy. She loves her bones and treats which i give her regularly.

Is this normal for an older dog to do? What does your older dog do all day??
