Didn't read the full thread - but here's what our vet said - don't do it or have the groomer do it until there are signs that your dog needs them expressed (scooting etc.) otherwise it will stimulate them and then it's almost like a production thing where the more they are expressed the more you will need to get them done. Vet said around 1.5 2 years of age she notices dogs will either start needing them expressed or won't and will be fine - usually it's the small dogs and the large dogs that end up having issues.
Pluto was fine until around 1.5 and now we have to have his done every few months... |
