Frogs are amphibians, animals that spend part of their lives under water and the remainder on land. They have long, powerful jumping legs and a very short backbone. Most Frogs have teeth (in the upper jaws only) but toads do not have any teeth.
Adult Frogs are characterised by long hind legs, a short body, webbed digits, protruding eyes and the absence of a tail. Most Frogs have a semi-aquatic lifestyle, but move easily on land by jumping or climbing. They typically lay their eggs in puddles, ponds or lakes, and their larvae, called tadpoles, have gills and develop in water. Adult Frogs follow a carnivorous diet, mostly of arthropods, annelids and gastropods. Frogs are most noticeable by their call, which can be widely heard during the night or day, mainly in their mating season.
Life cycle: Like all amphibians, Frogs spend their lives near water because they must return to the water to lay their eggs. Frogs eggs are laid in the water. When they hatch into tadpoles, they breathe with gills and swim using a tail. As they mature, they lose their tail, and they develop lungs for breathing air. In harsh climates, Frogs bury themselves in sand and mud and hibernate (sleep very deeply) through the cold winter.
Diet: Frogs eat insects, catching them with their long, sticky tongue. They also eat small fish and worms.
Classification and Evolution: Kingdom Animalia (animals), Phylum Chordata, Class Amphibia (amphibians), Order Anura (Frogs and toads). The first true Frogs evolved during the early Jurassic period, about 200 million years ago (during the time of the dinosaurs).
The distribution of Frogs ranges from tropic to subarctic regions, but most species are found in tropical rainforests. Consisting of more than 5,000 species described, they are among the most diverse groups of vertebrates. However, populations of certain Frogs species are significantly declining.

Tips For Housebreaking Your Pit Bull Terrier Puppy Dog
House-breaking your Pit Bull puppy requires a lot of time, effort, and patience on the part of the owner. There is no set time-frame on when your puppy will be able to do this, or how long it will take, you just have to start a routine and stick with it until it is finished. Many owners lose patience with their dogs due to problems that often arise during the house breaking process. It is important to just work through them as they come, and to remember not to punish your puppy, but work through this process together.
Many things can be done along the way that will help make housebreaking faster and easier for you and your puppy. As with any type of training, you have to be consistent with the routine. Take your dog out at the same time everyday, or if you aren’t able to, make sure that someone else can. The puppy will soon learn when it is time to go, and eventually will know what is expected of him. You should have everyone else in the household alerted to the routine, and willing to help when needed. Sometimes it is helpful to keep a journal of your dog’s habits, so that if they turn into a problem later, it will be easier to correct them.
You should also try to go outside with your puppy so that you can be sure he is going to the bathroom while he is outside, which will help avoid accidents while inside. If you are unable to go out with your puppy, he should be confined to one area such as a crate, or fenced in backyard, so that he can learn this is his space to go.
One thing that can interrupt the housebreaking process is irregular feedings. It is important that you feed your puppy the same amount at the same time everyday, and try to avoid giving him extra snacks and treats until he is successfully housebroken.
The most important thing when housebreaking your puppy is to be patient and understanding. He is going to learn overnight, and there will be messes along the way. You have to understand that this takes time, and try to maintain reasonable expectations of your puppy. It is important not to punish your puppy when that happens, rather just clean it up and accept it for what it is, part of the process. You will have a much better relationship with your puppy if you are patient with him as he grows.

Ridding Your House of Fleas
Chances are if you have pet's you have had to deal with the almost inevitable flea infestation. All pet owners know that once a flea infestation has gripped your living space it can be the start of a long battle.
In order to properly rid you home and pets of fleas you will treat the infestation as a whole. The fleas do not only live on your pet. Some research indicated that fleas spend less than 15% of their time on you pet. The rest of the time they are comfortably tucked away in a variety of warm places. Your carpet, your couches and even in your garden.
Summer and warmer weather will also bring out these evil little critters. This is because the warmth speeds up their life cycles. Depending on where you live you could face a flea problem all year around.
RECOGNIZING INFESTATION
Chances are you will know all about a budding flea problem. Fleas leave itchy bites on the ankles and beyond and make life for everyone in the area a misery. Fleas also leave telltale black or dark brown droppings.
One way to gauge the severity of the infestation is to comb your dogs coat over a white paper. The number of dark crumb-like bits that fall onto the paper will indicate the seriousness of your infestation.
If the fleas are leaving a lot of bites on the people in your home you will know the infestation is bad. Calamine lotion will provide some relief if the itching is bad. You can also experiment with one of the many natural repellents. Various substances rubbed on ankles or exposed skin will help keep the fleas from biting the humans; so you can concentrate on killing all the fleas.
THE DANGERS OF CHEMICALS
Many experts agree that the current chemical warfare on fleas is doing little to lesson the problem. Not only are these chemical treatments ineffective; they are also dangerous.
The dangers of these chemicals being ingested by dogs or even your children are high.
And there’s the fear that repeated, prolonged use of these chemicals is creating a new "super flea'. Eventually fleas will become completely resistant to our treatments. This evolution of fleas will create a need for stronger and stronger chemicals. Who knows what kinds of super chemicals we'll need 50 years from now.
Those in favor of natural flea remedies claim that natural treatments work better than the chemical ones. In order to treat the problem effectively you will need to adopt a holistic action plan.
