Dog Tired at 3 months

I've had a few people asking "how's Chico?" He's doing fine- weighs about 25 lbs and loves his dog food!
His new thing is to chew my hair looking for fleas as he does his flea bite- It's all cute fun and games; til he clamps down and pulls! OUCH!
He's a little tired from playing at the time of this photo-the only time he would sit still. LOL
