I love my dog! In fact, I actually consider him a family member. If you have a pet, I'll bet you feel the same way. We tend to get attached to our animals like this. They become such a huge part of our lives. At times it's difficult to even recall what it was like without them. My daughter barely remembers life without our black lab. We adopted him when she was three years old, and he's been with us for the past five years. But one thing I've come to terms with is that not everyone likes pets, and not everyone will appreciate your animal like you do. Some might even fear them. This is not so odd. If you encounter a large dog out in a park, who happens to be strolling with the owner, you won't necessarily trust their actions. Not if you have children. A part of you becomes alert. You know in the back of your mind that the dog could possibly react in some negative way toward you or your child. Hey, animals are unpredictable like that. And this is why dog training collars were invented.
You love your German Sheppard or Rot Weller, right? If this is really the case, you'll consider controlling them when out in public. You can do so with dog training collars. If you don't care to put your pup on a leash, you can always purchase a shock collar. These devices work off of a remote control, which the owner keeps in hand. If the dog should decide to disobey, the owner can send a small shock to the K-9 via the collar. In return, the dog will begin to behave. I believe these dog training collars are crucial for the dog and the owners' safety. As far as the dog is concerned, this is the perfect way to keep them from bolting out into traffic. And in regards to the owner, the remote shock collar will grant you the ability to stop your dog if he/she decides to abruptly leap at some other animal, or worse, a small child. Like I mentioned before, animals are unpredictable.
Try your local Pet's Mart for dog training collars. They generally offer quite a selection. This is where I purchased a shock collar for my dog. And if the dog collar fails to work, you can always return it. I did exactly this with a cat shock collar once. Now remember, keeping your animals safe means keeping you safe as well.
