I have previously worked at a vet and currently work at a doggy daycare and can administer many different medications (including shots) and have no problem caring for elderly animals, as I, myself, had a dog for 15 years and cared for all of her many medical needs. I currently have 2 dogs of my own, both small, and I have no problem walking large dogs. I am also very comfortable with skiddish or aggressive dogs. I am very passionate about animal care and would love to be a part in making you days easier and set your mind at ease knowing your pets are in great hands! *I am currently living with my mom and sister who also have cats and dogs, all small except one medium sized dog and they are all very friendly. The cats are usually hiding so no worries if your dog doesn't like cats*
