I absolutely love dogs and cats and am completely comfortable in working with them although I'm not a professional I do however have years of personal experience with cats and dogs.i have no problems in walking a real big dog I can keep proper control and I'm very alert and have attention to detail.i know when a dog or cat is upset or needs to use the bathroom.i have my own dog I walk as much as I can he is really nice.also used to live out in country working with animals had all kinds of animals I was around.i also had a relative who breeded small dogs and I would help out with the puppies I really love cats to and look forward to working with animals
