I'm concerned about Knox's jumping. He's a sub five pound male. He's in good shape. I feed him healthy food. We walk about a mile almost every day.

He's very happy and excitable, and he loves jumping from the floor to the couch, from the couch to the chair, off the top of the back of the chair to the floor...you get the picture.

Is there anything I can do to limit the risk of joint damage from the constant jumping. Watching his weight seems obvious enough. He jumped off the couch the other morning, and for the first time he hurt his front leg. He limped for a few minutes, but within fifteen minutes he was right back at it. He hasn't shown any other signs of discomfort since then. I have carpet, which cushions the impact somewhat, but it still worries me. I wonder if giving him glucosamine supplement would be a good idea. He's only a year old.

Thanks for any suggestions.

PS...My best friend calls him frogger. This four pound dog is literally flying around half the time at eye level. It's ridiculous. lol
