Pet care experience

Species appropriate care!

Rosie’s path to dog training began with a curiosity about animals that started early. As a teenager, she went to vet camp and attended a spay & neuter program which exposed her to animal health and hands-on veterinary care. Those early experiences sparked an interest not just in caring for animals, but in understanding how health, environment, and behavior intersect. That curiosity eventually led her into professional animal care and welfare. She spent several years working hands-on with dogs before joining Animal Care Centers of NYC (ACC), where she gained experience with animals across a wide range of temperaments, histories, and behavioral needs. Working in a high-volume shelter environment - particularly with anxious and behaviorally complex dogs.. Over time, behavior and training became the natural focus of her work. Rosie has continued to deepen her knowledge of relationship-based and balanced training, behavior modification, play-based training, socialization and neutrality, and breed-specific care. Training her own service dog has been one of her most formative experiences, giving her an up-close understanding of how relationship, consistency, technique, and clear communication come together to create reliable behavior in the real world. Rosie’s curiosity extends beyond traditional dog training. She is deeply interested in the foundations of whole-animal wellbeing including nutrition, husbandry, enrichment, physical health, genetics, and environment, and how each can influence behavior. Her experiences with both dogs and cats have reinforced her belief that behavior rarely exists in isolation. Today, Rosie brings that perspective to her work with dogs and their people. Rather than focusing solely on commands or correcting unwanted behaviors, she wants to understand the individual animal - their temperament, instincts, history, environment, needs, and relationship with their person - and use that understanding to create training that is thoughtful, practical, and built for everyday life. Rosie is currently engaging in ongoing clinics and applied training focused on canine behavior, training foundations, behavior modification, enrichment, and handler communication.

Rosemary Mills is uniquely gifted to care for and train your animal companions. Her knowledge of nutrition, training methodology and animal behavior is unparalleled among Rover sitters. In truth, Rover should create a whole new category for providers such as Rosemary. I highly encourage anyone who wants first rate care, training, or simply animal behavior information to hire this young woman. She’s the best at her job I’ve ever experienced!

Rosie has been a total game changer for me and my dog. We live in NYC and honestly he used to be a mess anfter moving here. Not great with people and always on edge. We tried a few other trainers before and they were too pushy or didn't listen to what he was telling them. This was really different. Rosie knew exactly what he needed and she also helped me understand what he was trying to say to me. I can read him better and he trusts me more. I don't have to worry about him freaking out and making someone feel scared or uncomfortable, and she got him to a point that he isn’t as scared or uncomfortable (and I know how to accommodate him now to avoid overstimulation and stress). It feels like a weight off my shoulders. I'm just really thankful we found her and for all the help she’s been!

I met Rosie while working together at an animal shelter, and I can confidently say she is one of those people who just naturally connects with animals. She is amazing with both dogs and cats and has a great ability to understand what an animal needs in the moment, whether that’s exercise, enrichment, comfort, patience, or simply some space. Rosie is incredibly attentive to both the emotional and physical needs of the animals in her care. Even her own cats are so well trained and engaged that they practically act like dogs! Animals seem to feel comfortable with her almost immediately, and it’s really no surprise why. She is also an amazing communicator and an absolute pleasure to work with. Rosie is positive, dependable, caring, and genuinely lights up every room she walks into. I’ve loved working alongside her and getting to know her, and I would absolutely trust her to care for my own pets. Any pet would be lucky to have Rosie looking after them!

Rosie is an amazing resource for issues with your pets’ behavior! I have two cats, both male, one 4 and one 2 - the younger of the two is a little bully! Rosie gave me recommendations on how to deter his mean behavior and over the last two weeks I have seen significant differences in the aggressiveness and frequency of the bullying. Alone time!! Thank you Rosie!!!

I can't recommend Rosemary highly enough as a pet caregiver. She has over three years of professional experience working with both dogs and cats in city animal shelters and private dog daycare settings, so she brings a wealth of knowledge and hands-on experience to every animal she cares for. What truly sets Rosemary apart is her calm, kind, and confident presence. She has a gentle way with animals while also knowing how to establish trust and provide the structure they need to feel safe and secure. Pets seem to instinctively gravitate toward her...they sense her positive energy and respond to it with ease and affection. Whether your pet is playful, shy, energetic, or needs a little extra patience, Rosemary has the experience and compassion to meet them where they are. I would trust her completely with my own pets and would recommend her without hesitation to anyone looking for a reliable, knowledgeable, and genuinely caring pet walker, sitter and care giver.

I highly recommend Rosemary as a pet caregiver/trainer. She is responsible, dependable, and genuinely loves animals. Rosemary is patient, attentive, and treats every pet with the same care and affection she would her own. You can feel confident knowing your pets will be safe, well cared for, and given plenty of love and attention while they're with her. Any pet would be lucky to have Rosemary as their caregiver/trainer!

Safety, trust & environment

Safety is my #1 priority. I firmly believe that a trained animal is a happy animal! Every animal that comes into my care has clear expectations so everyone can thrive to the best of their ability. If at daycare, I have the ability to crate and separate dogs and I have a clean, fenced in backyard that has a doggy pool for those warm summer days! For check ins and walks, i'm all about what is most comfortable for the pet. If your cat just needs someone to clean their litter box, thats what I'm there for! Wether its a potty break or full adventure, I'm here for it!
