Known to be among the most friendly of the hound breeds, the Beagle was developed to be a pack hunter. The best qualities in the Beagle are its fondness for exploring the outdoors and its enthusiasm for trailing. This independent breed barks, howls, and sometimes runs off on a trail on its own. Because it is also an incredibly tolerant, calm and adventurously playful dog, the Beagle also makes a perfect pet for families with children.
And before you decide to buy a puppy, consider whether an adult Chihuahua might better suit your needs and lifestyle. Puppies are loads of fun, but they require a lot of time and effort before they grow up to become the dog of your dreams. An adult Chihuahua may already have some training and will probably be less active, destructive and demanding than a puppy. With an adult, you know more about what you’re getting in terms of personality and health and you can find adults through breeders or shelters. If you are interested in acquiring an older dog through breeders, ask them about purchasing a retired show dog or if they know of an adult dog who needs a new home. If you want to adopt a dog, read the advice below on how to do that.
The American Pit Bull Terrier (APBT) is one of the most most popular dog breeds. Unfortunately, even after long periods of domestication, there is still a lot of controversy surrounding them and related Pit Bull breeds. This is often due to misunderstanding and misinterpretation of their nature. The truth is that Pit Bull breeds can be among the most loving, affectionate, loyal and beautiful companions a person can have.
Despite the many endearing qualities of the Chihuahua, if you’re thinking his tiny size makes him a great choice for children, you’d better think again. The Chihuahua may be just right for traveling around in a puppy purse, but he’s far too small and fragile for even the gentlest of children's games. Chihuahuas also tend to be high-strung and prone to nipping, snapping and even biting when frightened or threatened, or when defending his people or territory.
Beagles are active, energetic dogs who need at least an hour of exercise every day. This doesn’t mean just letting them out in the backyard. Beagles were bred to work in packs and are happiest when they have company. A Beagle who is left alone inside or outside for long periods of time will tend to become destructive. This can be avoided if he has a companion (whether human or canine) to play with. Beagles are escape artists, so an exercise area must have a fence at least five feet tall that extends underground to prevent tunneling. Walks must always be taken on a leash, because as a scenthound with a very strong hunting instinct, a Beagle will not be able to resist the urge to run off in pursuit of a compelling scent.
In a 2014 literature review of dog bite studies, the American Veterinary Medical Association (AVMA) states that breed is a poor sole predictor of dog bites. Controlled studies have not identified pit bulls as disproportionately dangerous. Pit bull-type dogs are more frequently identified with cases involving very severe injuries or fatalities than other breeds, but the review suggests this may relate to the popularity of the breed, noting that sled dogs, such as Siberian Huskies, were involved in a majority of fatal dog attacks in some areas of Canada. Bite statistics by breed are not tracked by the CDC, AVMA or the American Society for the Prevention of Cruelty to Animals (ASPCA). State Farm Insurance spokeswoman Heather Paul stated "Pit bulls in particular are often misidentified when a bite incident occurs, so reliable bite statistics related to the dogs’ breed are unreliable and serve no purpose." The White House stated that "the Centers for Disease Control and Prevention looked at twenty years of data about dog bites and human fatalities in the United States. They found that fatal attacks represent a very small proportion of dog bite injuries to people and that it’s virtually impossible to calculate bite rates for specific breeds". 
And, as far as dogs are concerned, I would love love to have a Bully friend :-) Currently I am mostly thinking between American Staffordshire Terrier, American Pit Bull or American Bulldog. American Bulldogs I know pretty well, Staffordshire some and with the Am. Pit Bulls I haven't had longer experiences. So, please, if you have some article or words of advice which could draw some more detailed comparison, please share. I have of course googled it all, but it all comes down to similar as I thought – they are similar in temperament, only American Bulldogs are better guards and generally a bit calmer/slower (more mastif, less terrier). All of them very gentle, loving, athletic. Is there something more or different you would say?
Finding a good breeder is the key to finding the right puppy. A good breeder will match you with the right puppy, and will without question have done all the health certifications necessary to screen out health problems as much as possible. He or she is more interested in placing pups in the right homes than making big bucks. Good breeders will welcome your questions about temperament, health clearances and what the dogs are like to live with and come right back at you with questions of their own about what you’re looking for in a dog and what kind of life you can provide for him. Most breeders like to keep the pups until they are 12 to 14 weeks old to ensure that they are mature enough to go to their new homes.
The merle coat pattern, which appears mottled, is not traditionally considered part of the breed standard. In May 2007, The Kennel Club decided not to register puppies with this coloration due to the health risks associated with the responsible gene, and in December of that year, formally amended its breed standard to disqualify merle dogs. The Fédération Cynologique Internationale, which represents the major kennel clubs of 84 countries, also disqualified merle. Other countries' kennel clubs, including Canada, Australia, New Zealand, and Germany, have also disqualified merle. However, in May 2008, the Chihuahua Club of America voted that merles would not be disqualified in the United States, and would be fully registrable and able to compete in AKC events. Opponents of merle recognition suspect the coloration came about by modern crossbreeding with other dogs and not by natural genetic drift.
