Itchy Dog: Causes and Solutions

Itchy skin, excessive scratching, persistent licking, hot spots, rashes, ear problems, face rubbing, skin redness, paw chewing, irritable behavior, scabbing, low energy and loss of hair! WOW… quite a list of behaviors that might be driving you and your dog crazy!


Capstar Flea Tablets

Capstar Tablets begin killing fleas within 30 minutes. Studies show that the tablets are over 90% effective against adult fleas on dogs within 4 hours and cats within 6 hours. In addition to the typical irritations associated with an infestation, fleas can transmit parasites, and also be responsible for skin conditions on your pet such as flea allergy dermatitis (FAD) on dogs, and miliary dermatitis on cats.

Actively controlling flea infestations is important to the health of the animal and reduces the problems associated with these parasites. The active ingredient is Nitenpyram.

Capstar Tablets are best for:

  • dogs, puppies, cats, & kittens 4 weeks of age and older
  • pregnant and breeding animals
  • quick kill for heavy flea infestations on your animal
  • daily use (effects last approx. 24 hours)
  • dogs and cats over 2 lb

Not Intended for use on:

  • dogs and cats under 2 lb
  • puppies & kittens under 4 weeks
  • long term control of fleas (kills for approx 24 hours.)

    "Excellent Product "

    I live in the South and my cats are indoors, but somehow we still manage to get a few fleas during the warm months. Used once a month with Advantage II for cats keeps them at bay. Since I have bug bite allergies, this keeps both me and the cats sane.

    "Amazing Product"

    I have a cat that is allergic to everything. I cant put any of the topical flea products on him. I purchased Capstar and it was fantastic. I gave him a Capstar along with a bath and his fleas were gone. I now give him 1 once a month just incase he is a inside cat and once a month just keeps him protected. I have told all my friends and they are all now using Capstar. GREAT PRODUCT>

    "3 dogs"

    This is the best product I have ever used but I need something that will last longer than a day. I have 3 dogs ranging from 55-120 pounds, with ages of 6,13, and 14. Cannot afford the flea problem.

    "I could not believe it!!"

    I could not believe how well Capstar worked!!! We have fought a flea infestation for months on our 2 yellow labs...I tried everything!!! The poor dogs were at the point of losing their hair and having scabs on their body from the many flea bites, and I was at my wits end!!! I took a chance and bought it!!! I gave the dogs one tablet each at around 5 pm, by the next morning...NO FLEAS!! I could not believe it!! I am sold on Capstar!!! Only side effect I noticed, was a little lethargy the next day...but they are doing great now!!! AWESOME PRODUCT, and IT REALLY WORKS!!

    "Always worked"

    I have used Capstar for my Rottweiler/Shepard mix for several years, and she's an outdoor dog. I never saw her scratching, nor any fleas on her. One tablet usually worked for a month. Easy to use - I just stuck a tablet in a piece of weiner, but she would eat it out of my hand, too.

    "works great"

    This product workds great! I had tried shampoos, drops, sprays, powders and nothing would stop the fleas...until Capstar. It only has one major flaw that would stop it from working...The pet has to actually swallow the pill and keep it down, lol. Pets will pick up a pill and walk away and spit it out when you are not looking. You have to make sure the pill gets swallowed. Put it in some favorite snack or something, if you do it will work.

    "does not work"

    We tried this product and at checked the dogs at 2 hr intervals, and it did not work at all! What a waste of money!
