Brad Croft of Universal K9 trains shelter pit-bulls to assist police officers in fighting crime and searching for people. The success of the program can be seen around the country as more police departments express interest in these dogs. Also, even the most grounded person can be devastated by the loss of a pet. Dr. Guy Winch is an authority on broken-hearts and has answers to common questions following the death of a pet. He says you should avoid the 5 common mistakes when grieving the loss of a pet, including not getting rid of reminders like feeding bowls and leashes and feeling guilty about getting another pet. Also, If you’ve ever been nervous around a dog and told to just be calm because dogs can “smell fear,” well, that is good advice though most people can’t suddenly calm their fear. Believe it or not, the sentiment behind that guidance is rooted in some truth. While dogs probably can’t literally smell fear, they do seem to respond to fearful people with more aggression according to a new study in the British Medical Journal. Also, the stories of unruly flights caused by animals continue to grab headlines around the world, like the one where a woman attempted to bring her pet peacock onto a flight out of New Jersey’s Newark airport. The woman was told the big bird would not be allowed on the plane even though the owner had bought a separate ticket for the peacock. United Airlines issued a statement saying the peacock did not meet guidelines for a number of reasons, including its weight and size.
