Welcome to Just Answer. My name is Jane. I have been involved professionally with dogs in the healthcare and behavioral fields for over 20 years. I’ve worked as a Vet Assistant and Behaviorist and have extensive experience in dog reproduction, as a breeder, for even longer than that.. Canine behavioral issues and training are also my specialties. It will be my pleasure to work with you today.
This could be a few different things. The most likely cause is dental issues. Puppies chew everything because they are teething and the chewing helps relieve the discomfort of the teeth coming through the gums. Dogs instinctively chew when they have mouth discomfort. Given your dogs age and small breed, it would be very common for him to have dental issues.
Check your dog’s mouth for tartar on the teeth, possibly red gums, darkened teeth, broken teeth or something caught between the teeth or gums. Additionally, an oral exam by the Vet can rule this out. Buffered aspirin can be given to a dog with a dosage of up to 5-10 mg per pound every 12 hours for pain if a tooth is the issue.. Keep in mind that a dog's body does not metabolize aspirin in the same way as a human and thus should not be given more than a day or two without contacting your Vet. The aspirin may need to clear your dog’s system before other medications can be given, so keep that in mind if you decide to give aspirin and be sure and tell your vet when your dog is seen. Read side effects and precautions here.
Now the other possibility is that your dog is starting with Cognitive Dysfunction Syndrome (CDS) which is like human alzheimers. There is a wonderful site that explains it well and also explains how to document your dog's behavior and discuss it with your vet. Often a dog will revert to behaviors they had as pups like chewing. Other symptoms are a break in house training, being found in odd places like behind doors or furniture and even barking at people he should know.
The good news is that if there is a problem there is a drug called L-Selegeline (Anipryl (R)) which has been recently approved for use in the clinical indication of cognitive dysfunction (CDS) in dogs. Read this site for other drug choices.
Please see this site for more information and other causes that may exhibit the same symptoms.
I would go ahead and schedule an appointment with your vet to have a dental checkup done on him especially if the aspirin seems to help curb his chewing a bit. You might also try a kong with treat compartment. You fill the compartment with peanut butter that does not contain xylitol or with yogurt and then freeze it. Give it to your dog when it is frozen and this usually takes a dog several hours to lick and chew the contents out of the kong. This will help save your household items.
You need to prevent chewing on cords as he can electrocute himself. Even if he seems fine, it can cause problems with his heart. One trick is to run them through pvc pipe.
