Got a puppy, breeder said don't start heartworm meds until 4 months old—is that normal or should I be worried?

We just brought our new puppy home, and the breeder advised us not to start any heartworm medication until he's 4 months old. I'm a bit concerned because I want to make sure we're doing everything right to keep him healthy. Is this standard advice, or should I consider starting sooner for his safety?

Answer

It's understandable to be concerned about your puppy's health and when to start heartworm prevention. Generally, veterinarians recommend starting heartworm medication earlier than 4 months to ensure your puppy is protected.

  • Heartworm prevention is crucial for your puppy's health.
  • Many veterinarians recommend starting medication from as early as 6-8 weeks.
  • Consult with a vet to tailor a plan specific to your puppy's needs.

Heartworm disease can be a serious condition in dogs, as it's caused by parasitic worms transmitted by mosquitoes. Typically, puppies can begin heartworm prevention safely as young as 6 to 8 weeks old. It's always best to consult with a licensed veterinarian who can provide guidance based on your puppy's specific health needs and local mosquito prevalence.
