NO, this is really dangerous for the dog. Frontline for 40lb dogs is 4x as strong as Frontline for 10lb dogs, and the increased dosage is poisonous to the dog.
I would not recommend it. I do know you should never put the canine Frontline on a cat. You should use the canine Frontline for the dog according to his weight and the same for a cat, use feline Frontline only. Why mix them?
No. Frontline products should be used on the specified species. This is because one of the main components of Frontline, S-Methoprene is needed in a higher dose in cats. This is because it does not last as long in a cat than in a dog. So, if you used Frontline for dogs on your cat, it may not be as effective. However, this higher dose is still safe to use on a dog - so you could use Frontline for cats on a dog.
Any breed of dog can have Frontline.
Frontline by itself should be sufficient to deal with your cat or dog's flea problem. Using a flea bath will reduce the effectiveness of the Frontline (you should only wash your dog with a gentle shampoo to maintain Frontline's protection).
Once a dog is 8 weeks old, you can use Frontline - there is no weight requirement. There are different doses for different weights, so select the one that most closely matches your dog's weight.
One other way besides Frontline to get rid of fleas is to use PetArmor.
If you have multiple cats, you should treat them all with Frontline Plus application at the same time. You may want to keep the separate right after the application to cut the risk of them licking the medication off each other.
Absolutely NOT- only use medication for dogs for dogs and medication for cats for cats!
No. The only approved flea treatement for ferrets is Revolution, which is usually available from your vet. You can use the kitten dose of Frontline to treat your ferret for fleas, just use one drop per pound of ferret. (2lb ferret= 2 drops)
According to Frontline, it is safe to use Frontline Spray on puppies from 2 days old and Frontline Plus on puppies from 8 weeks of age.
At 8 weeks old, the kittens are a little too young and using Frontline flea treatment may do more harm than good. The safest method for kittens this age is to use a flea comb on all the kittens, and comb them twice a day until no adult fleas are seen.
No, Frontline is for fleas on dogs and cats. Horses get Lice. Use lousepowder. Frontline is likely it orritate the horses skin.
