The dog’s snout should never be smacked to discourage biting, aside from the fact that negative reinforcement is not an effective training mechanism; smacking the dog’s snout can even encourage a firmer grip. Puppies chew to ease their teething discomfort and replacing the item being bitten with an item that is acceptable is the best way to discourage a negative biting behavior. One other method that is recommended by some trainers is to take your thumb and place it over your dog’s tongue gently holding the bottom jaw with your other four fingers. While holding the tongue, tell your dog “no” firmly and then let go. Repeat this process if biting continues.
Crate training can be helpful for some dogs if they learn that the crate is their safe place to go when left alone. However, for other dogs, the crate can cause added stress and anxiety. In order to determine whether or not you should try using a crate, monitor your dog’s behavior during crate training and when he’s left in the crate while you’re home. If he shows signs of distress (heavy panting, excessive salivation, frantic escape attempts, persistent howling or barking), crate confinement isn’t the best option for him. Instead of using a crate, you can try confining your dog to one room behind a baby gate.
In addition to Benadryl and homeopathic treatments, your veterinarian may recommend a prescription drug for your dog’s anxiety. Most of these anti-anxiety drugs can be administered orally and are best suited for your pet prior to the anxiety-inducing situation. Because anxiety medication typically takes at least 30 minutes before they start working, it’s best to give it to your dog ahead of time rather than waiting until they present symptoms.
