I've now cared for dogs and cats for over 20 years. My secret to be a good carer is to simply love your animals. All it needs is a combination of kindness, silliness, understanding your dog's needs and providing an infinite amount of playtime while ensuring their safety! They give the love back and can't wait to do it again!
I live in central London, so I will in general bring your dogs to Regent's park or Hyde park. If your pets like playing, be reassured, I do to!
