Both products are FDA-approved and provide the same protection against heartworm disease, roundworms, and hookworms. Tri-Heart Plus is an FDA-approved alternative that contains an identical formulation.\u003c\/p\u003e\n\n\u003ch3\u003eQ3: What is the minimum age for using Tri-Heart Plus heartworm prevention tablet in dogs?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eAns:\u003c\/strong\u003e Tri-Heart Plus can be used in dogs and puppies that have turned 6 weeks old. Any puppy younger than this should not receive the tablet. Before starting, all dogs must also be checked for an existing heartworm infection by a licensed veterinarian.\u003c\/p\u003e\n\n\u003ch3\u003eQ4: Is Tri-Heart Plus ivermectin pyrantel chewable safe for pregnant or breeding small dogs?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eAns:\u003c\/strong\u003e Yes. Ivermectin\/pyrantel has shown a wide margin of safety at the recommended dose in dogs, including pregnant bitches, breeding males and females, and stud dogs. In clinical trials, the combination was also safely used alongside many commonly administered veterinary products.\u003c\/p\u003e\n\n\u003ch3\u003eQ5: What should I do if my small dog misses a dose of Tri-Heart Plus monthly heartworm tablet?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eAns:\u003c\/strong\u003e If the 30-day dosing interval is exceeded, give the tablet immediately and resume the regular monthly schedule from that point forward.
