The advantages and disadvantages of having dogs
Some people have just always wanted to own a dog.For others it's a new concept,but one that they're very interested in pursuing.Whatever your initial reasons are for wanting to bring a dog into your world,there are a number of benefits that they offer,some of which you might not have even thought about or realized were possible.
Dogs offer a source of protection,whether from a pint-size Chihuahua's barking to a Rottweiler's often-intimidating demeanor.If you live alone,have small children,or are often on the road leaving your family more vulnerable,and you want a security system that doesn't run on electricity or batteries,think about the benefits that a dog could potentially provide for your sense of peace as it pertains to feeling safe.
However,some people insist that they dislike dogs to some extent.There are several reasons why they hate dogs as below:
1.They are dirty.They lay down their dog shit wherever they are - On your lawn,on my lawn,in their own beds,on your bed.
2.They smell.They need to be washed like a car otherwise they infect uphostry (couches,carpets,curtains) with their stench.
3.They render owners backyards unusable.Don't you dare walk back there with bare feet!
4.They need so much attention.They go mental if they are left alone for long periods of time.
