I haven't done any professional pet care. But I've had a lot of experience watching dogs and lizards. I myself have a ferret, two lizards, and a cat living with me. In the past I have taken care of a few guinea pigs and I believe two frogs. I have an easier time with dogs. I've had to take care of puppies on numerous occasions too. I don't normally mind them on the couches or beds. I'm used to taking care of small-medium sized dogs but in a few cases have had to watch some bigger ones. Since I was around animals for most of my life, I have gained plenty of experience when it comes to both training, and just taking care of them
