It is generally not recommended that you put a flea collar on a 12 week old puppy. While flea collars can be effective in protecting dogs from fleas, they are not as safe or effective on puppies due to their developing immune systems. Furthermore, the strong odors from some flea collars can cause irritation and even respiratory distress to puppies, so it’s best to avoid using them altogether.
The best way to protect your puppy from fleas is through regular grooming and cleaning of bedding material. Vacuum carpets and furniture regularly and wash your puppy’s bedding with hot water whenever possible. In addition, talk to your veterinarian about finding the best preventative for your 12 week old pup – this may include monthly topical solutions, oral chews, or shampoos specifically designed for treating flea infestations. These products are formulated with younger animals in mind, so they are less likely to cause harmful side effects.
Putting all together
12 week old puppies are not yet ready to wear a flea collar due to the potential side effects it could have on the puppy’s health and wellbeing. Pet owners should stick with a topical solution specifically made for puppies aged 8 weeks or younger to ensure safety.
