To prevent the breed from developing problem behaviors you should start training early and make sure that the dog gets plenty
of exercise and mental stimulation on a daily basis.
While you may think that letting your cat outside is a wonderful way for him or her to
get exercise and mental stimulation, it will also put your pet at risk for a wide range of feline health concerns that could shorten your pet's lifespan and put your animal at risk for a wide range of potential health problems.
Even though dogs bark for many reasons including excitement, anxiety, for attention or to sound the alarm, the best prescription for any barking issue, whatever the cause, is usually
increased exercise and mental stimulation which helps refocus a dog's mind and tire her out, therefore reducing the need to bark.
My friend is heartbroken and guilt - ridden, but realizes the only option is to rehome the Mal, who needs much
more exercise and mental stimulation than she and her husband can offer (though they do try).
