Introduction:
There are many species of animals that share a bonding with the humans.. Foremost among them, the mans most loyal friend has always been the Dog. Humans and dogs h***e been inseparable for thousand of years depending on each other for protection and survival. From earlier days we h***e relied on dogs for hunting and guarding and now more as pets for companionship, protection and their showmanship.
Dogs belong to the family Canidae which includes wolves, jackals and foxes. All modern domestic dogs (Canis familiaris) h***e descended from the grey wolf. There are now more than 300 different breeds of domestic dog and these are often classified into different groups according to the tasks such as hunting, guarding and herding, for which they were originally bred.
SELECTING A DOG:
You h***e to give a lot of thought and take your own time especially if you are a novice, before picking a dog you are going to live with the next ten or fif*** years. A bad or hasty or careless decision can mean a lot of heartache and waste of money. There are a number of factors to be taken into consideration before deciding on your choice.
First you must h***e an idea of the different breeds and groups of dogs. Then you should pick one which should suit your personality and your needs( whether you need it for guarding, hunting, showing or just as a companion) and the time you can spare, the space you can provide, the money you can spend etc.
Once you h***e decided on a particular breed, the next thing is to pick out a healthy one from the lot for sale. It is always better and safer to get a pet from families with dogs h***ing a recent set of off springs so that the puppies are not exposed to the array of diseases found at pet stores, kennels, breeding farms etc. and you also get an idea about the animals parents. Another option is to get it directly from a good breeder or a small familiar pet store
No matter where you get your pet from, h***e it checked out with a veterinary doctor and make your purchase only on his certification of good health. As far as possible get the necessary papers from the seller like its Pedigree ( a list of the dog's forbears say parents, grand parents and great grand parents etc.) and its registered name, its AKC registration Number/ AKC registration Certificate if any etc. If not, you are entitled to know about the parents, its heritage and background as some breeds are prone to h***e genetic weaknesses. The seller should give information about the dogs medical history outlining the shots it has had and its food habits etc.
The best age for picking a puppy is at eight - nine weeks, after the weaning and before he/she has gotten used to their birthplace. The pup should h***e clear bright eyes and clean ears. Reddened or swollen eyes is not desirable. Discharge or pus from the eyes can indicate worms. Ears should smell waxy not foul. Lightly clap your hands from behind while somebody is standing in front to check hearing. The nose should be free of discharge. Sneezing, coughing, wheezing or a runny nose and eyes can indicate Canine distemper in puppies. The teeth should be white and clean and breath should smell clean. Check the skin for patches of flaking, reddening and for signs of fleas and the fur should be shiny in most breeds. While you want to ***oid overly nippy pups, don't pick the one that flinches or cowers when you approach either: Puppies should be active but not aggressive. Over-all the animal should feel firm, strong and energetic.
The dog (Canis lupus familiaris) is a domesticated subspecies of the wolf, a mammal of the Canidae family of the order Carnivora. The term encompasses both feral and pet varieties and is also sometimes used to describe wild canids of other subspecies or species. The domestic dog has been (and continues to be) one of the most widely-kept working and companion animals in human history, as well as being a food source in some cultures.
The dog has developed into hundreds of varied breeds. Height measured to the withers ranges from a few inches in the Chihuahua to a few feet in the Irish Wolfhound; color varies from white through grays (usually called blue) to black, and browns from light (tan) to dark ("red" or "chocolate") in a wide variation of patterns; and, coats can be very short to many centimeters long, from coarse hair to something akin to wool, straight or curly, or smooth.
