Usage
Designed for everyday use, this spray is perfect for home grooming sessions, outdoor adventures, and before boarding. Apply 8‑12 inches away from the animal, spraying from the tail upward until the coat is fully saturated. Gently fluff the fur while spraying to ensure even distribution.

FAQ
Is the spray safe for cats?
The formula is specifically tested for dogs and is not recommended for cats due to differences in skin sensitivity. Use a cat‑specific product for feline flea control.
How often should I reapply the spray?
For optimal protection, apply the spray once a month or after your dog has been in a high‑risk environment such as a park or boarding facility.
Can I use the spray on puppies younger than 12 weeks?
No. The product is formulated for dogs older than 12 weeks. For younger puppies, consult your veterinarian for a suitable alternative.
Will the spray damage my dog’s coat?
Because it is water‑based and free of harsh solvents, the spray does not dry out or damage the coat. It actually helps maintain a healthy shine when used as directed.
Does the citrus scent attract insects?
The citrus fragrance is designed to be pleasant to humans and neutral to insects. It does not attract additional pests and may even deter some.
