Although I haven't had any "professional" experience I have kept and cared for animals my entire life, including; hamsters, rabbits, guinea pigs, cats, fish (marine and tropical), dogs and exotic birds. I have cared for many other people's pets before also. I have experience with a variety of different sized dogs and have owned dogs as little as a jack Russell terrier to as big as a Doberman pincer and am very comfortable and confident with any breed of dog. I completely disagree with breed stereotypes and believe each dog will show you the same behaviour you show to them.
