The sooner a problem can be curbed the better. As blind people we can't always see a physical problem. Medical care for guide dogs is not cheap. Everything that is worthy has a price. Guide dog users gladly pay for medical services for their best friend.
Some animal hospitals offer reduced rates or free office visits for service dogs.
All one has to do is ask. Guide dogs like house pets need play time. How they play is of great importance. Guide dogs are not allowed to play with things like frisbees and balls. These are things that are found in every day life and can cause a guide to be distracted on walks.
