My experience into dog care started 9 years ago, and my time working with cats started less than a year later. My experience of both dogs with a hyper or dissociative personality and felines with bad temperament was mostly gained while working at various animal shelters. Some shelter dogs and cats are not temperamental on their own but sometimes will instinctively react to those who are being the aggressors, as is their nature. it's often very similar at dog parks- A Gathering of many unknown dogs, some likely to be reactive to others and always a few having chance of causing a fight. Something I keep in mind for safety every time I have an interaction with a dog I don't know while walking someone else's that I was entrusted the care of, is that other animals I don't know will always be unpredictable. Outside my charity work for shelters, for an even longer amount of time I've taken care of pets of many ages and breeds for family/friends going on 9 years now. I have handled many large breeds; Labradors, Huskies, Great Danes, German Shepards, Mastiffs. I have also worked with various medium and small sized breeds. My total 2 years of experience with puppies was spread out caring for and helping raise pups my sister had gotten. Between raising puppies and trying to work with pets giving me a hard time during the course of my many dog sitting jobs I have seen and learnt countless things about our furry friends! To list a few; common dog and cat habits, nutrition, toxic foods for dogs, signs of aggressive body language in pets, and abnormal behavior alongside possible causes.
