You’ve given me plenty to work with. The strongest points for your profile are your lifelong experience with dogs, current hands-on experience with multiple breeds, understanding of behaviour, secure home, and genuine focus on making owners feel worry-free.

I’d keep the tone warm and personal, while avoiding making you sound like a professional trainer or veterinary professional. Here’s a polished version:

I’ve been around dogs and cats since I was a small child, with dogs always being a big part of my life. Growing up, I had experience with breeds including Border Collies, Rottweilers, American Bulldogs and German Shepherds, and as an adult I had two dogs of my own — a Pomeranian and a Maltese. Although I don’t currently have pets of my own, I regularly care for my sister’s two Basset Hounds and Rottweiler, and I also walk and groom two Newfoundlands.

I’m calm, patient and confident around dogs of all sizes, and I have experience handling different personalities, including reactive dogs. I’m not a professional trainer, but I understand the importance of recognising a dog’s boundaries, behaviour and individual needs. I also have connections with people experienced in dog behaviour and nutrition, which is useful when understanding different approaches to care.

For dogs staying at my home, I have a three-bedroom house with a secure fenced front drive and enclosed backyard. A typical day can include walks, exercise, play, feeding, relaxation and following any routines you have established for your dog. I’m happy to accommodate small to large breeds, provided they are suitable for my home environment.

I also offer dog walking and pop-in/check-in visits. For walks, I generally take no more than two dogs from the same household at a time, with the distance and type of walk depending on their size, fitness and leash skills.

My goal is simple: to care for your dog as I would my own and give them companionship, attention and a safe environment while you’re away. Most importantly, I want you to feel completely worry-free knowing your dog is in good hands.
