In the examples below, notice that transportation and park ticket prices stay the same even when the number of days changes. If you're staying somewhere that's relatively inexpensive and not eating out all the time, you can often extend a trip from 4 to 7 days for very little money.
Some seeing eye dogs are selected from breeders specifically because they possess a certain temperament that is required of service dogs. However, many seeing eye dogs are rescued from animal shelters. All dogs who enter the training program to become seeing eye dogs must past a series of rigorous personality tests. If the dog passes the tests, they are then taken to a training facility.
There are basically two ways for a dog to get blue eyes. Some breeds just produce a lot of blue-eyed dogs (Aussies - eye pictures - or northern husky-type breeds are examples). Blue eyes are a recessive gene, so the dog must inherit blue as both eye-color genes. There is no relationship between this type of blue eyes and deafness. Some dogs have what I would call lack of color blue eyes (if you look at the pictures above, you will see that Gwen has very pale, almost white, blue eyes).
