Hi, I wonder if you can help me. My Cockapoo Prince will be 5 in September and has always been able to jump into the car. However, just lately he goes into a springing position but can’t manage the jump. This morning, he was trying to jump on my bed, something he absolutely loves. He tried desperately three or four times, again going into the springing position but unable to make the jump so my husband had to lift him up onto the bed. Does anyone have any idea what might be wrong with him. Any help would be greatly appreciate.
