I agree, that a good diet will usually eliminate anal gland problems HOWEVER many dogs are not on good diets. Many dogs that come through my shop are fed grocery store brands and suffer from more than only anal problems. If these dogs do not have their anal glands expressed than the risk of impacted glands and even ruptures are raised. I have been trained to express anals during my grooming course, even had a vet watch me to make sure that I was not doing this improperly. Most grooming courses will teach a groomer how to do anals. Infact, all the grooming salons in my area offer this procedure.
Once you start expressing you always have to do it. If the groomer doesn't get all of it it can become infected and then they have a vet visit anyway. Let the vets do it.
I disagree. This is a misconception that once you do this you always have to do this. The foundation of this myth lies in that a dog who has anal gland problems usually has a reason for them being so and instead of addressing the problem the glands are simply expressed time and time again. For example, a less than ideal diet will can be the root of the problem, but instead of changing the diet to a better one the owners will get the glands expressed again. And also, a dog does not always express their own anal glands fully when having a BM and they do not risk getting an infection because they were not fully eliminated. Infections occur because they are impacted or have a bacteria that causes the infection.
I have to further explain my routine. I DO check every dog that comes through for a groom, HOWEVER not all of them require an expression. So when I said that I do all of the dogs that come through, I only meant that they are all checked and the ones who do require the procedure get it. I certainly don't poke and prode at a dogs bum when they do not have full glands. But daily I see dogs who do need this procedure.
I see no reason to send all of my clients to the vet when I run into a full anal gland. They are already in my tub and I am professionally trained on the procedure. They are already paying for a groom, why should they have to pay for a vet visit when I am fully competent to express the gland. If they choose to have a vet do this, than by all means! It is a messy job and I want my clients to be happy with whatever they choose.
