It is often a dog's natural instinct to lick an injury or wound. While dogs often lick to help reduce the pain or eliminate the irritation, excessive licking can make the injury worse. Licking the wound can impair the body's ability to heal itself and may drastically slow the healing process. If stitches are involved, licking can open the incision and disturb the wound. The bacteria in the saliva of dogs can also cause serious infections. Luckily, there are several ways to stop your dog from licking its wounds.

Building a wooden birdcage is a relatively simple project that will ensure you will wind up with exactly the cage you are looking for to house your birds. Before you start, it is important to identify what kinds of birds you will be keeping and if you would like a freestanding birdcage or one that hangs from the ceiling. Plan where in your house you will be keeping the birdcage so you can plan if you would like to build a square, round or rectangle cage.

There are plenty of places that would be happy to receive a used dog house for dogs in need when you no longer need it. Local animal shelters, dog rescue organizations, humane societies and kennels are a good place to start. Be sure to check with the organization first, though, as some may have restrictions as to what kinds of dog houses they will accept as a donation.

Fish tank canopies or hoods can be made to fit the dimensions of any size tank. Making your own tank canopy saves a lot of money, and makes your aquarium more personalized. Aquarium hoods cover the top of the tank and house the light ballast. A metal reflector is installed inside of the hood to shine more light into the tank. It also reflects any radiant heat that the light bulb sends out back into the water to help regulate its temperature.

Mutualism is a relationship between two different organisms in which both benefit from the association. This is the relationship most people think of when they use the word "symbiosis." Although the tiger is a solitary animal, it too has it's share of mutualistic relationships that help it survive. Without these relationships, tigers would have become extinct long before the hand of man forced them on the verge they are on today.
