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.
Atopica is a medication used to treat skin allergies in dogs. The benefits include reducing itching and inflammation. However, potential side effects may include vomiting, diarrhea, and decreased appetite. It is important to consult with a veterinarian before using Atopica for your dog.
Benadryl is a completely different type of drug to Atopica. Atopica is often used for allergys especially skin problems (perhaps this is what is wrong with your dog?). It is a very good drug and acts to dampen down the inappropriate immune response your dog is experiencing helping her feel more comfortable and less itchy. Benadryl is not licensed for use is dogs and comes in a strength made for humans, not a little Maltese! Please, please don't use it on your dog. She is on one of the best drugs for allergys there is. It isn't worth risking her health just to save some money.
Any breed of dog can have Frontline.
Atopica can help manage your dog's skin condition by reducing inflammation and itching, leading to improved skin health and overall comfort. It can also help prevent flare-ups and reduce the need for other medications.
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.
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.
One other way besides Frontline to get rid of fleas is to use PetArmor.
You can not apply frontline on a cut or bleeding blister no.
