Finding the right flea prevention for dogs is key to their health. The Happy Jack Flea and Tick Treatment Spray for Dogs is a new formula that contains two active ingredients which kills fleas and ticks instantly and keeps them off for weeks. DD-33 is water-based (unlike similar sprays which are up to 40% alcohol) and therefore gentle to the skin and hair. Happy Jack DD-33 instantly kills fleas and ticks, including ticks that cause Lyme disease, and helps prevent new infestations on dogs and cats. This flea control for dogs is formulated for minimum toxicity to dogs and cats, including the most sensitive breeds. This flea spray for dogs comes with an easy-to-use trigger without aerosol noise trauma or solvent irritation. Happy Jack DD-33 instantly kills fleas and ticks, including ticks that cause Lyme disease, and helps prevent new infestations on dogs and cats. Great to use before or after walks, hikes, yard play, park visits, grooming appointments, and other times pets may be exposed to fleas and ticks. Happy Jack has delivered dependable flea, tick, and mite control for over 80 years, giving pet owners a proven treatment from a long-standing American brand.

Q: Do I dip or spray the dogs ? I have 7 dogs and how much product do I need to use ?

  • Happy Jack Support
    A: Thank you for your question. Dd33 is a topical 16 oz spray to prevent flea and ticks, not a dip. We also have kennel dip in a concentrate mixed with water that can be used for flea and tick treatment and prevention as a dip, sponged or mixed for a spray application. Instructions are 1/2 ounce per gallon of water. Either option DD33 or Kennel Dip would treat multiple dogs.

Best product

7 days ago
Happy Jack flea spray don't burn or irritate your dog . It helps repel fleas . Leaves no residue and absorbs pretty good . I spray all my dog products on myself first, to make sure they don't burn my 11 dogs skin . I had a problem with a different product for fleas that burnt and stung my dogs . So I try everything first .

Good service.

I was greeted by a lady working the counter and asked if I needed help finding anything. I knew what I wanted and where the product was at in the store. I brought my item to the same lady at the checkout and was asked for my phone number and logged my transaction.

Yes, I recommend this product.
