Many shoppers search for Seresto collar instructions before they order. The most important instruction is simple: use the correct pet-specific collar, read the label before applying it, and keep the package directions for reference.
Start With the Right Collar
Choose a dog collar for dogs and a cat collar for cats. Dog and cat flea and tick products are not automatically interchangeable. If you are shopping for a dog, compare the small dog collar and large dog collar. If you are shopping for a cat, use the cat collar.
Fit and Use Checklist
- Read all package directions before applying the collar.
- Confirm age, weight, and pet-type guidance on the label.
- Fit the collar so it is secure but not too tight.
- Check the neck area regularly for irritation or rubbing.
- Wash hands after handling if the label instructs you to do so.
When to Ask a Veterinarian
Ask a veterinarian before use if your pet is very young, elderly, pregnant, nursing, taking medication, has sensitive skin, or has had reactions to flea and tick products before. If your pet shows concerning symptoms after use, follow the label directions and contact a veterinarian.
