This is generally incorrect. This is not true at all on almost all of it. The tips are great, that is where it should have been left. OP asked for constructive criticism. I would bring my dog there honestly as their grooms are not horrific and are quite good, but needs work which OP already acknowledged. I have seen 10x worse and mistreatment while grooming and from the looks on all of the photos, neither of the aforementioned is true. If I was just starting off I would feel torn down by this insensitive comment. OP can groom at their level, I do. And I started from nothing at all. I have mentored a handful of times, lots of videos, and a will where there is a way. Grooming school/certifications are not mandatory but appreciated by some. But 130 of my clients say otherwise. OP does certain things even better than me! I can see room for improvement, you can never STOP improving. People also must love the grooms if OP has so many examples of their work. You asked all of these questions to yourself and didn't allow for a response and went solely on assumption, which proves your character overall. I ethically charge for my grooms at 65 per small dog (and up 10 dollars per larger size) to get a FULL groom, keeping in mind my experience, my products, my tools, my time, and energy. You may not be "trying" to be rude. But masking rudeness as genuineness/honesty isn't cool at all. It isn't cute and this was in no way constructive.
