I have been a dog owner myself, as well as I have volunteered in an animal shelter for 2 years, so I am incredibly fond of dogs, cats and all other kinds of pets. As I am now a student who has moved away from home (so away from my family pets as well), I miss having animals around a lot. Additionally, since I’ve encountered all sorts pets in all sorts of states and traits, I take the time to introduce myself first, figure out the animal’s needs and only then move further with the care. 
I have 7 years of experience in taking care of dogs and cats, including the experience at the shelter. I have no preference for pets I sit, as well as I am rather flexible with my schedule - I can be available mornings, afternoons and evenings. I am a loving, gentle and caring sitter, described as "the one that has a way with animals." I find walking and/or sitting them genuinely pleasurable, so I always try to make the visits as warm as possible. Nonetheless, I am aware of the responsibility such care entails and make sure to do everything in my power to avoid any kind of negligence.  
When petsitting/boarding, I send regular photo updates, don’t leave the animals alone (unless allowed), walk them 3x a day and let them wander freely but safely around the apartment. I walk them regularly to provide toilet breaks as needed, but in cases of little accidents inside the apartment, I make sure to clean it up and generally to keep the pets in safe and higienic conditions. In addition to the > 15 minute walks, pets receive plenty of play time to fulfil their physical activity needs. I remain in consistent communication with the owners and feed/walk/provide medication/etc as instructed by the owners. I also spoil the pets with snacks, if allowed:) 
Fresh water is always available, as well food is provided as required by the owners. I try to stick to petsitting one animal at a time due to the stress different pets may cause to each other, but if allowed by the owners, I am always happy to sit a few animals at once. In case of an emergency, I will bring the pets to the vet or act in any other required manner as indicated by the owners. 
When dog walking, I take at least 30 minutes, keep my copy of the key safely, always check if everything is secured before leaving, dress the pet in provided attire if needed, carry the pets up/down the stairs if needed as well. During house visits, I spend at least an hour with the pets, playing with them and making sure they’re fed, walked and happy. 
I am also happy to house sit if that is preferred by the owners. If agreed in accordance with my schedule, I can house sit for an indefinite time. When house sitting, I always double check if everything is locked/turned off before leaving and/or night time. 
According to my regular clients, their pets are always excited to come back to my place - hope that would be the case with your pets as well:)
