Pets Plus Us vs Sonnet: customizable vs simple

By PetAssured Editorial Team Last reviewed : June 8, 2026 6 min read

Quick Answer

Pets Plus Us is the customizable pick; Sonnet is the simple, online pick. Pets Plus Us lets you tune reimbursement (70/80/90%), deductible, and a wellness add-on, and it's available broadly. Sonnet (underwritten by Petline) keeps it to two tiers with up to 80% reimbursement, a fully online experience, and annual dental cleanings built into its Comprehensive plan — but it's only sold in some provinces. Choose Pets Plus Us if you want to fine-tune the plan; choose Sonnet if you want simplicity and included dental and it's offered where you live.
