Don’t forget that the way that dogs walk on their feet means that if you hear the nails clicking on the floor, the toes are being bent back. This can contribute to arthritis in the feet.
When I was working, we did have dogs that we didn’t want to stress by trimming their nails at some particular time. All of them had heart issues and if stressed, they would turn blue. One particular dog, we met in the parking lot and trimmed a couple nails, then the next day or so, we would get a couple more, and so on until the job was done. Some could safely be tranquilized. Some, we could teach the owners how to dremel the nails at home.
