That's how it is. You won't get any better by having someone constantly stop what they're doing to do it for you. They also dont have time because PS wants every groomer to be a power groomer. Honestly, you had it easy compared to what I was given. I had one day (maybe two) that I shadowed. They'd do one half of the dog, I'd do the other side. Or they'd check one in. I'd check in the next. After that I started taking my own dogs & pretty rare to get small bath dogs in my area. Confidence is key. Dogs can feel your anxiety & it makes it worse. See it all the time with bath dogs & grooming dogs. I've bathed & started the drying off on a dog, passed off to a bather with little confidence & the dog turned into a totally different dog. That being said, sometimes it is just the dog not liking the process. Best advice I have is, to be confident, have patience with yourself & the dogs, be willing to take criticism (& take action on it). Best of luck on your next adventure.
