Stumped!!

For the last few days, Joe has had difficulty eating dog biscuits and we have had to put water on them to soften them.
We took him to the vet today to see if his teeth were okay. She had a good look at them and couldn't find anything wrong, hence the title.
She gave us some anti-inflammatory to give him in case his jaw muscles are sore.
I bought some special dogs treats at the vets.
I had to drop something off. I was out of the car for less than five minutes but by then, Lucy had managed to eat the entire contents of the bag!!!
This lovely song  was on the radio on the way back
