I have 3 years of dog experience. Our dog has allergies so I am familiar with special dietary concerns, as well as seasonal allergies and giving medication. We do not have a fenced in yard, however, dogs are never off leash or chain and I am personally outside with them at all times. The house is dog proofed and there are lots of toys to play with. I am comfortable walking very large dogs as long as they have been trained to walk on a leash.
