I've grown up with dogs and cats my entire life. I have experience caring for, walking, feeding and washing them. I grew up with big dogs -- german shepherds + a south african boerboel -- so am aware of the strength required to walk such a large and powerful animal at times :) I am equally comfortable working with smaller dogs as well. As for cats, our family cat used to have diabetes, so I am comfortable giving insulin injections if your cat falls into this category as well. Please feel free to ask me any further questions!
