Hi I have a 5 month old cavalier king charles and she HATES it when i try to lay her on her back to rub her belly. If i pick her up and put her on her back her legs all go stiff and point up and her eyes look like she sow a ghost. I thought dogs loved getting their belly rubbed??? (can i just ask if its normal for a dog not to eat when anyone is around???, when i leave her food she just leaves it unless i put it in her crate and shut the door, then when i return 2 mins later its gone).
