These dogs are an incredible and useful tool that our Police, and military are able to use for a number of different tasks. Losing breeds like the German Shepard could be very detrimental to our police force here in America and our military overseas. They are used as guard dogs, attack dogs, they help find drugs and bombs, and help to rescue people. Without these dogs, the productivity of the forces that keep our country safe may be greatly diminished. The German Shepard is a charismatic, intelligent, useful, and affectionate dog breed and these characteristics make it the perfect candidate to receive the vaccine for the retrovirus.

The sentence "They are used
The sentence "They are used as guard dogs, attack dogs, they help find drugs and bombs, and help to rescue people" doesn't quite work, instead you could split this into two sentences.
I would recommend to refrain
I would recommend to refrain from using the word "these" so frequently. Instead, be more specific.
I am pretty sure that you do
I am pretty sure that you do not need to capitalalize police in the first sentence.
