Canine Behavioral problems

Excessive barking, chewing, scratching, digging, coprophagia …these are some of the common behavioral problems of dogs. Barking is a dog thing. The same thing is true with digging and chewing. These behaviors become a concern when done excessively. Dogs are territorial and very protective of its people but when but a dog that becomes very aggressive will be a concern of the owners.

How are parasitic diseases associated with behavioral problems?

Internal and external parasites per se would not make a dog suddenly turn into a blood thirsty animal that would attack people on sight. Internal parasites will not make the dog unlearn its housebreaking training. Internal parasites however, would cause the malfunctioning of digestive system resulting in loose stools that the dog is incapable of controlling. The dog will be confined in a place where it cannot soil the home. The severe itching caused by flea, tick and ear mite infestation would irritate an owner causing the dog to be moved to the yard. Generally, dogs are loving animals, they want to be with their people but due to parasitic infestation, these animals are rejected, isolated and even punished. Would it be surprising if they develop behavioral problems?

Causes of Canine behavioral problems

The history of the dog is often times associated with the development of a behavioral problem. A dog that was rescued from a center would manifest either an aggressive or an extremely shy personality. Some breeds are noted for their stubborn personality so that housebreaking and obedience training would be a challenge. What most owners do not know is the fact that behavioral problems can evolve from a parasitic disease too.


Puppies with histories of severe roundworm and tapeworm infestation are noted to be burdened with hypermetria when they mature. Puppies are commonly vaccinated against distemper, hepatitis and other diseases. Deworming puppies though are often times neglected. Most owners are not aware of the serious effects of internal parasitism. One of these adverse effects is hypermetria. Dogs with this condition are noted to be very aggressive and to be incapable of long term memory making training difficult.
