Is Adams flea and tick spot-on safe for my 11-year-old small dog?

The small dog dose should be sufficient when she is borderline between small and medium. You should also treat all bedding, sleeping and resting areas with an insecticidal household flea spray as 95% of the flea burden is present as eggs and larvae in the environment and only 5% are adults on your pet. Be sure to treat all in contact animals and treat with a dewormer active against tapeworms as these can be transmitted by fleas

Oh no, how frustrating! I would not recommend using Adams flea and tick products for dogs of any age, as they tend not to be terribly effective and can lead to some serious reactions. Your puppies are currently too young to be treated with any oral or topical flea and tick preventatives. However, one method of managing fleas at this young age is to bathe the puppies in original Dawn dish soap weekly. The original (blue) Dawn will kill adult fleas, but it will not kill eggs or treat the recently hatched larvae. Be sure to dry them well and keep them warm after their baths since young puppies are not able to regulate their body temperatures as well as adult dogs. By 6 weeks of age, your vet can prescribe Revolution to be used topically, or you can purchase K9 Advantix II OTC when the puppies are 7 weeks old. Also be sure to wash their bedding and any soft materials they contact in hot soapy water. Assure that the puppies' mom and any other dogs in the house are also receiving flea and tick preventatives regularly. K9 Advantix II is labeled as being safe for pregnant and lactating bitches. I hope that all goes well!

No, this would not be recommended. Given the weight difference, you would likely need multiple doses which could easily lead to overdose. Use a product specifically for dogs. Talk with your veterinarian about the safest, most effective options.

Advantage is available OTC and it's both safe and effective. It's a topical product that you apply directly to the skin. Follow package directions carefully, and be sure you purchase the appropriately sized product for Harper.

In my opinion flea collars are not a good idea any more (except the seresto collar) as they usually contain carbamates which are liver toxic. It would be better to use a spot on, for example. Here are some products: Spot-ons and/or chews Advantage, Advantix Advantage Multi (Advocate in the UK) Frontline (ticks as well) Bravecto spot on (ticks as well) - for cats, in tablet form for dogs Simparica, Nexgard Revolution (stronghold in the UK) Tablets: comfortis (will only kill fleas once) Collar: Seresto (ticks as well)

As long as it is a cat approved product and not a dog product an the wright ranges are correct then it is fine to use. A small amount of cats have an allergic reaction to any topical product where there can be hair loss at the application site but if this has never happened before then it is unlikely to happen now

I would recommend Frontline plus as it is the safest for dogs that small. Also, I believe comfortis has a size for really small dogs but this product only controls fleas, not ticks. I hope this helps!
