I can't beleive a vet can be so naive, that he gets caught that way
I do my dog's glands when they are in the bath. . . . . .
Mind you, brings to mind when I 1st started to breed, I had a bitch in season and wanted to take her to be mated, so was testing her reactions to tickling her rear end, daily.
This particular day, the stud dog owner asked me to test her, so I did. I leant over her & sure enough she flicked her tail, hitched up her back . . . . . . . . . . . . . and emptied her glands, in my face !!!!!!!
