I know he's a puppy, but shouldn't there be something instinctually built in that says to stay away from a cactus?
I got most the large quills out, but he still has a bunch of tiny ones. I sat on the floor with him and a tweezers and tried to pull them out. I had to bribe him to be VERY still, but overall he was good and didn't flinch when I pulled them out. He had a large one in his paw that he actually asked me to take out (sad face, paw held up) earlier. The quills that remain don't seem to bother him anyway.
Widget had some quills in her when she was a baby too - she learned I guess because she hasn't had a problem since!
I guess that's one hazard of living in Texas.
p.s. I took a few pics today but they turned out awful. Not sure why (very blurry). Tomorrow is supposed to be a nice day so I'll have the camera outdoors with us all afternoon. We'll see if we can capture the dotted duo doing something cute
