Dogs are man's best friends - this is a known and accepted fact now. They're all friendly, mood lifters and good-natured. But this is one thing you need to know – dogs belong to the wolf family. Now, this doesn't make them dangerous or something to get scared of, but they do have those aggressive traits which can make them potentially harmful if aggravated. If you ensure that you don't irk them, they're completely safe! A dog is extremely loyal and will go to any extent to protect his master. So the mere far-off probability that the dog may harm you should not keep you away from petting one. Are you also interested to know about cat just visit catnip and cats site.
