Denise is the only person we trust with our Leonberger. We use her for let out services and occasionally for boarding services. Denise is extremely professional and personable. It was difficult to find a person that we would be comfortable having in our home while we are not there but Denise has put our mind at ease. She is amazing with our dog and he loves her - which is all we could ask for.

We have had Denise come in for our cat care since 2015. It is so nice to have worry-free vacations, knowing that we have a reliable and friendly caregiver coming in daily. Our cat is calm and happy when we get home, which is so wonderful.

Suzanne, Pickering, October, 2018

We have been using Denise's services for about nine months for dog-walking and occasional grooming as well as boarding and cat visits when we go away. Working with Denise has been an amazing experience! Our young lab is very strong and high energy. Through her daily walks she has benefited from Denise's training methods and her behaviour has improved significantly. Our dog loves her and we consider Denise a member of our pack. We would not hesitate to recommend Denise and her services.

Like all pet owners, leaving our pets is like leaving members of our family. Relying on Denise to take care of my two cats Mick and Bowie provides me with a sense of comfort when I am away. My one cat Bowie is extremely shy but Denise was able to change him from greeting her with hissing to greeting her with purring. Knowing that she cares enough to cater to each personality of my pets provides a peace of mind that is not easy to find in other pet sitters.

Carol, Pickering, August, 2017

We have been using Denise's services for the last two years. She comes to our home to check up on and visit our very old cat. She looks after him as if he were her own. She loves and is devoted to the animals she cares for and it shows. We can relax while we are away knowing that he is in great hands. We recommend using Denise without reservation.

We consider ourselves so fortunate to have worked with Denise in training our two puppies and in using her boarding services as well. She is an absolute delight to work with and it was a great experience for our whole family. Denise demonstrates excellent knowledge of training methods. She’s very intuitive in understanding pets within a family dynamic. She has consistently gone above and beyond in her services, and it is apparent that she absolutely loves what she does.Our family thinks of her as the puppy whisperer and we would enthusiastically recommend her services to others. Without a doubt, she puts her heart into her work!

We are a first time dog owners and very soon after we got our puppy, the joy and excitement turned into "What are we doing wrong?!" We started reading books even before we became happy dog owners, but that wasn't enough. We knew then that we had to look for professional help and we tried a few trainers, but nothing really worked until we called Denise. Her approach with our dog, but most importantly with us, gave us back excitement and joy. Thanks Denise.

Milan, Whitby, March, 2016


We've been using Denise for over a year and a half now, both for dog walking, and for dog sitting. She's great with our fur babies and updates us regularly on anything she notices we might need to be aware of. She goes above and beyond when we've had emergencies and needed someone to pop in to let them out and give them a cuddle until we can get home. We highly recommend using her, someone who cares as much about your pets as you do, if that's possible!

Heather and Family, Ajax, July, 2015

When our daughter was invited onto the Competitive team at her dance studio, we were excited. Then we realized that it would involve travelling out of town a few weekends each year so we were worried about leaving Boomer, our beagle. Boomer is a rescue dog who suffers from anxiety separation. When we left him at home for the first time, he was so panicked that he broke out of his crate by bending the bars! So of course we were worried about leaving him at a traditional kennel. Fortunately we discovered Denise Holland (Denise’s Pet Care). Before we hired Denise, she came to our house for an “interview”. We could immediately tell how easily she and Boomer connected. And how caring she was. Although we were a little nervous our first trip, Boomer made it through with flying colours so anytime we have to be away now, our first call is to Denise. We believe that she treats Boomer like her own dog. And we, especially our daughter Gillian, love the personalized journal that Denise provides us with so that we can hear all about how Boomer did while we were away.Thanks Denise for keeping Boomer safe and happy for us!

Denise has been a fantastic service since we brought our two puppies home when they were eight weeks old. They’re now six months and we still need her as we both work and I’m often out of town. Having her come to our home has been such a relief and even though they’re older, it’s a long day for them without getting outside for a while. She’s so conscientious and leaves me a note every day when she visits. We also hired her for the in-home training as it’s been a while since we had a puppy and we weren’t sure about how to train two at the same time. She offers an incredible deal and will come to your home and work with the dog and their owners in their own environment. She offers excellent training lessons focusing on the dog’s total well-being – not just behavioural obedience - she includes nutrition, first aid, grooming, safety outside, and the rationale behind the way dogs communicate and socialize. I would strongly encourage you to hire her.

Angie, Ajax, March, 2014

After our daughter married and moved away, we no longer had our pet sitter. I had seen Denise driving around to clients and decided to call her and inquire about care for our cat Penny while we're away. Having been a former business owner/petsitter myself, my standards were very high. Penny and I hit it off very well with Denise. We’ve now found a great pet sitter to care for our cat while we’re away. We leave with peace of mind in knowing our much loved cat is being cared for by a great pet sitter who truly cares. Oh, and Penny loves her too!

Catherine S, Ajax, March, 2014


We have been using Denise's Pet Care for about six months now and are very happy with her service. She is great with animals and our dog Oscar really enjoys his walks. We really appreciate Denise's attention to detail and her journal of Oscar's walks is a great way to keep track of what he was up to. I would recommend using Denise's Pet Care.

In 2012 we decided to take a family vacation out of the country. We had only one cat, Theo at that time and needed to find someone that we could trust to take care of him as we would. We did our research and then called Denise. She was wonderful. She came to our house to meet Theo and to get to know us. In 2013 Denise also watched over not only Theo, but our newest addition Max during the weekend of the ice storm when we were out of town. She went to the house during that bad weather to ensure that our boys were fed, had water and had clean litter daily. That is the kind of person she is, she CARES! We would not hesitate to recommend Denise to anyone looking for a pet sitter. She is kind, loving and a true animal lover. We trust Denise to take care of our two cats Theo and Max and any other critters that come along. It gives us peace of mind to have someone as special as Denise watching over our beloved boys.

Nicole, Rob and Zach, Ajax, March, 2014


When our long term dog walker retired last year we were not sure where to go or how our dogs would adjust to a new walker. And then we met Denise. She loves dogs and takes great care of our boys. She has the patience to deal with both our senior dog and our pup. Scooter and Simon look forward to Denise’s visits each day.

Cindy, Ajax, March, 2014


Denise is awesome, kind and accommodating. My dog loves her and she takes great care of him. I really appreciate the fact that she was open to looking after him regardless of him being a pit bull. Knowing that she truly cares gives me the peace of mind to enjoy my vacation.

Colleen and Rob, Ajax, April, 2013


We would not hesitate to recommend Denise to any pet lover. From the first moment Piper met Denise, he's looked forward to her daily visits. It's clear that the affection is mutual. Denise makes sure that Piper's individual needs are met. She keeps up with our busy schedule and has housed Piper as a guest on very short notice when we had a death in the family and had to travel right away. It eases our minds to know that Piper is well cared for when we're at work. We're often given bits of advice and observations if Piper is acting out of the norm. If it wasn't for Denise noting that she saw a barely noticeable limp in Piper's gait, we would have thought it was all in our heads. We found that Piper had strained his leg while being his usual energetic self. This is an example of how diligent and caring Denise is with animals. She gives each animal all her attention and it shows in how happy Piper is. We trust in Denise to take care of our four-legged son and have felt that her and her family (dogs and humans alike) have become a part of our family! If you are looking for someone to give your furry and/or feathered family members some extra love, Denise is the one to call!

Sharon and Mike, Ajax, April, 2013


We would highly recommend Denise for all your pet's needs. Denise has been doing 2X weekday puppy visits with Jax since the week we brought him home last winter. We have also completed a puppy training course with her as well. As first time puppy owners, Denise has been invaluable. Denise is our go to person when we have health, safety and training questions. She is always there to provide advice and to reassure us. I can't imagine not having her in ours and Jax's life. Denise is very flexible, easy to reach, and accommodating with our hectic and busy schedule. Above all, she provides me with peace of mind knowing that Jax is getting all the fun and attention he needs and deserves during the day. We feel so lucky to have such a loving and diligent person taking care of our most prized possession!

Mike and Tracy, Pickering, August, 2012


Two months prior to moving to Durham our Yorkie had lost his 13 year old brother and was dealing with a lot of changes. We hired Denise to come to give him a mid-day walk. Within a week of visiting our home to meet us all, Denise was our regular dog-walker. We find that Bandit is happy and content when we get home. We appreciate the daily communication book where Denise tells us anything we need to know. We recently had Bandit groomed by Denise and couldn't be happier. She loves pets and it shows!

Heidi & Paul, Pickering, February, 2012


Denise has been a godsend to us and our pets. We needed special care for our animals over the summer while we travelled to Nova Scotia. Our Collie, Shelby, suffers separation anxiety, so we were particularly concerned about how she would be with such a lengthy absence - 2 weeks. When we left her for 1 week last year to go to Florida, she was very stressed upon our return, We didn't want the same to happen with a longer time away. Denise cared for all of our animals which included Shelby, 2 cats, 1 leopard gecko and a fish tank full of fish. Upon our return from Nova Scotia, we were so pleased to find that Shelby was in good spirits and there was no sign of stress or separation anxiety. I know this is because Denise spent quality time caring for Shelby as though she was her own lovable dog. We have found the best possible caregiver for our animals in Denise and for once I was able to go away without fretting over my animal family. Denise sent daily texts to advise us that all animals were okay - it was a tremendous relief for all of us to know that they were in such loving and capable hands. Shelby has never been keen on brushing and grooming but with Denise's one on one, Shelby actually looks forward to Denise's weekly visits. It is apparent that Denise puts her heart into every animal she cares for and they greet her with hugs and kisses. In addition, Denise has valuable insights and information about pet care which she shares readily with us. In my opinion, Denise is the best pet care person I have ever had to care for my animals. I'm very thankful to her and recommend her to anyone who genuinely loves their pets and wants the very best care for them. Denise is the BEST.
