The Best Time to Give Your Dog Heartworm Pills

Nothing beats early prevention. The sooner you start your dog on heartworm pills/medication, the sooner you will be
able to prevent infection. The good news is that help is readily available. You can consult your veterinarian, so he
or she can perform a diagnostic blood test and recommend the right heartworm pill based on the age, breed, and
lifestyle of your dog.
Some heartworm pills available are Interceptor, Sentinel, and Heartgard. Generic heartworm preventives such as NuHeart
are also for sale at very affordable prices.
When giving these medications, it is important to consider if the dog is old enough to start taking them. Doing so is
very important in ensuring your pet's safety. The manufacturers recommend that medicines like Heartgard, Heartgard
Plus and NuHeart
be given to dogs that are at least 6 weeks old and that Sentinel and Interceptor be given to dogs that are at
least 4 weeks old and weigh at least 2 pounds.
Depending on the heartworm pill prescribed, you may need to give it on a monthly or daily basis. Remember that there
is no need to give further medication than what is prescribed.
Thus, the Best Time Is Year-Round
It seems that the only way to prevent heartworm infection is to give heartworm preventives to dogs the entire year. As
long as you are aware of the best time to give them and you have the appropriate heartworm pill, you can help protect
your pet from heartworm disease. Now, there is no time to waste. Why don't you check with your vet and have your dog
start on a preventive heartworm pill today?
