5 Things you should never buy for your dog
#1. Rawhide Treats: when dogs swallow larger pieces of rawhide treats, they are in danger of damaging their digestive system. They are simply not safe, and are not worth risking hundreds of dollars of veterinary bills and a sick puppy.
#2. Retractable Leash: every time the dog pulls and you follow, it teachers your pup that they are in control of where they are going. Retractable leashes are the perfect "training tools" for teaching dogs to pull their owners.
#3. Training Time, without you: taking classes with your dog has just as much to do with teaching you how to work with your pup, as it does with the pup learning commands. Good instructors observe your interaction and make you a better handler. If you are planning to send your pup to a training camp without you, only half of your team (dog + handler) is learning their part.
#4. Popular Dog Food: before you purchase next bag of food for your dog, take a look at the list of the ingredients. What is #1 ingredient? What is #2 ingredient? What is #3 ingredient? If what you are seeing is grain fillers (corn, rice, etc.), then you need to reconsider your choices, and look for a healthier option. Dogs are carnivores, after all, and their diet should be based on meat.
#5. Electric Fencing: even without getting into the debate of whether or not it's a humane training method for you pup, consider the lessons your dog is learning. "When I see a passerby - I run to greet them, and I get a correction zap! When I see someone walking their dog - I run to greet the dog, and I get a correction zap! When I see someone riding a bike - I run to greet them, and I get a correction zap! That means, crossing the line, and(!) everyone who passes by our house can cause the zap! That's a bad thing - I'll consider them danger and will be sure to bark to tell them off." Let's face it, many dogs have barking and territorial instinct built in. Do you really want to emphasize through electric fence "training"?
Ultimately, it is every owner's personal choice on what they feel is the best thing for their pet. However, if you are considering investing into one of the items listed above, I strongly encourage you to do extensive research on the topic.
