Do Even Small/Toy Dogs Need Heartgard/Heartgard Plus?

Absolutely. It doesn’t matter what size the Dog is, they are still at risk of heartworms and they are still at risk of other intestinal worm issues as well. Buy the smallest pack size and ensure that you give once a month whenever the weather is warm enough for mosquitoes to thrive.

How to Give My Dog Heartgard Plus Chewables?

This could not be easier. As they are so tasty you will find that all Dogs love them. Simply offer them the chew and they will take it. If they swallow food without chewing though please ensure that you break it up into a good few smaller pieces. These are called chewables for a reason. Give them slowly and don’t let your pet gulp a whole one down in one go.

It works most effectively if they can be administered in a few pieces. This is not such an issue with small Dogs, but for larger Dogs with the larger mouth then it is very important to break the medication into pieces so it isn’t just swallowed whole.

What is the Difference Between Regular Heartagrd and Heartgard Plus?

The regular option will protect against heartworm disease and only heartworm disease. The Plus version will also help to control roundworms and hookworms. For the absolutely minimal difference in the price then it makes sense to me for everyone to get the extra protection  the Plus option gives.

Is it Needed in Winter When Temperatures are Low?

If you live somewhere where temperatures get below freezing or you have extended months of cold weather then mosquitoes are no longer an issue. WinterThis means that your pet cannot get infected and have the beginnings of heartworm disease. If you live somewhere like this then you do not need to use all through the year. The problem is that the only way to be 100% sure your pet is protected is to give every month.

The fact is that it is easy to forget to medicate for a month or two either side of the coldest weather, thus putting your pet at risk. So the best advice is to give once a month every month to ensure there is never any risk at all.

Expired Heartgard?

Never, ever, use any medication that has expired. Humans would never use medications like this on themselves, and it should not be given to a pet either. The date is there for a reason, so never risk it not working properly. As medications age they are not as effective, so always make certain that the date is very good before you give the protection your pet needs.

You will find that often they are cheaper but they do the same thing. The packaging is often of a lower and not as good but the protection that they offer is the same. The differences in prices is sometimes good but often minimal, so it is down to owners to simply buy what they feel most happy with.

Can You Cut Heartgard Chewables in Half?

They can be cut up to make giving to your pet easier and so they are digested better. But you should not cut up chewables if the size is wrong for your pet. It is always best to buy the right pack size and to give the whole chewable once a month. This ensures that they really are getting the exact medication they need, and takes the guesswork out of it entirely.

Is a Week Late OK?

Missing just a week is absolutely fine and nothing to worry about. Just be sure to give as soon as you remember and try not to make a habit out of it. Setting a simple reminder of one form or another is the best way to ensure that you give on the same date each and every month of the year.

    You mention that if your dog accidentally eats more than one dosage, to watch for signs of overdose. My concern is that I’m giving my 9 lb dogs a dosage that is appropriate for up to 25 lbs. Am I not overdosing them by more than double? It seems if the dose is enough to be effective on a 24 lb dog, then it’s too much for my 9 pounders. Is there a reason why you can’t have a pill dosed for smaller dogs considering there are so many of them and a lot of us are concerned.

    Please let me know.

      Hi Bonnie, if the manufacturer says the pill is suitable for a dog that size then I wouldn’t worry. But if the pill is meant for larger dogs then I would check with them to be on the safe side.
