Flies

Flies will only go to your dog if it is dirty, unwashed, or very unhealthy. You should stop your dog from getting into the garbage or rolling in refuse.

Fleas

For fleas, you can Buy an all-in-one tablet to prevent fleas and bugs from infecting your dog. (Sentinel Spectrum etc.)

For a more immediate results, there is a formula (pill) called quarterzone. You can get in a supermarket. It kills fleas for only twelve hours, but fleas die as quickly as 5 minutes after the dog takes the tablet.

You can also get de-fleaing shampoo, which leaves a repelling chemical on the fur.

I'm white and a swimmer have been for 13 years. Since I was 4, and in 2004 there was a black guy on Michael Phelps relay and they had the greatest race I've ever seen. But in a general statement i would say they aren't as my black swimmer friends would say "there's no water in Africa"

(1) If the question is "Are black/Negro people good swimmers on average", the answer is NO. Particularly in the United States, but also in the U.K. and other developed countries, there appears to be a black cultural problem with teaching their children how to swim. Even controlling for economic disparities, far fewer black people can swim well than any other race of Americans, with the next "poorest" swimmers (latinos) having over DOUBLE the percentage of people rated "fair" or better at swimming. There is some historical context to this cultural issue, but it bedevils many sociologists to explain exactly how and why this anti-swimming bias exists in the black community. Statistics bear this out: a black person is more than 10 times as likely to accidentally drown than white person. Outside of the developed world, the lack of suitable pools, lake, or rivers in areas with large back populations seriously hampers the ability of blacks to get even the opportunity to learn to swim well, and even when such facilities are available, the cultural fear of water causes a strong disincentive to learn to swim.

(2) If the question is "Can the average black person be as good a swimmer as other races?", then the answer is YES. There is nothing inherently different enough about black people vs everyone else that makes swimming harder for them. It is no harder for the average black person to become a good swimmer than a white, asian, or latino person.

(3) If the question is "Are the top black swimmers as good as the top swimmers from other races?", then the answer has to be NO. Firstly, due to #1 above, large portions of black people refuse to swim, which significantly lowers the pool (no pun intended) of talent available to draw from. In addition, very slight genetic differences that are invisible at the average person's level become highly magnified at the top athlete level. The type of body optimal for swimming (generally, tall, lean, moderate musculature and muscles which produce a relatively high continuous power output) seems to be much less common in the elite black athlete, and more concentrated in the white and asian population. All this boils down to statistics - for the tiny percentage of each race that has the physical characteristics to be an elite athlete, blacks (and to a lesser extent, latinos) do not tend to have the body most suited for swimmers. Similar situations are seen in other sports; for instance, sprint running is heavily dominated by blacks, as is long-distance running. There are few asian basketball stars. Samoans are disproportionately represented as NFL linemen, but there are few Samoan wide receivers.

A final note about this: defining someone's race is extremely difficult, as outward appearances lie. Genetic analysis has shown that external appearance has very little to do with the actual relationship a person has with another. For instance, many African tribesman are more closely related to the typical Southern European "white" than they are to their neighboring African tribes, even though skin color would seem to indicate otherwise. Making generalizations about race is very, very, tricky, as the concept of "race" is poorly defined.
