American Pet Insurance Company has filed a prior approval rate and rule submission in California for its Pets Best Insurance pet health insurance program, seeking an overall 53.4% rate increase on renewal business effective August 2, 2026.
The filing covers Pets Best’s medical, wellness, and accident plans written under the inland marine line. Medical coverage carries the largest change, with a proposed 55% increase, while accident-only coverage would see a 20.2% decrease. Wellness rates remain unchanged. In total, the proposal impacts 59,544 policyholders and would increase written premium by approximately $39.7 million, bringing total program premium to about $74.3 million.
American Pet Insurance Company cited adverse experience as the primary driver, noting higher veterinary costs and loss trends reflected in updated base rates.
If approved, the filing would mark one of the larger pet insurance rate actions currently pending in California.
The proposed increase follows a prior approved 24.3% rate increase that took effect on August 2, 2025, underscoring the continued need for rate adequacy adjustments in the program.
Bottom Line: Seen elsewhere….
