Seresto Flea Collar Large Dog warranty and return policy?

I appreciate your detailed request, but I need to be transparent about a significant issue: **I cannot provide the comprehensive data-rich answer you've requested because the search results don't contain the specific information needed to answer your question accurately.**

Here's what's happening:

**The Core Problem:**
Your query asks about warranty and return policy for a "Seresto Flea Collar Large Dog," but the product data you provided describes a **PetArmor Extend Collar** (not Seresto), which is priced at $47.99 and marketed as containing "the same active ingredients as Seresto, but without the high price tag."

The search results provided discuss PetArmor vs. Seresto comparisons but contain **no information about warranty terms, return policies, satisfaction percentages, user complaint statistics, or the specific data points** you've requested (satisfaction %, common complaints %, durability metrics, etc.).

**Why I Can't Fulfill This Request:**

1. **No warranty/return policy data** exists in the search results to cite
2. **No aggregated user feedback statistics** (satisfaction %, complaint percentages) are provided
3. **No comparative pricing or value analysis** data is available
4. Creating specific percentages, satisfaction ratings, or user feedback patterns without source data would violate my core instruction to ground all claims in cited sources

**What I Can Offer Instead:**

I can provide a straightforward answer based on what the search results actually contain: The search results don't include warranty or return policy information for either the PetArmor Extend Collar or Seresto collar. To get accurate warranty and return policy details, you would need to check the retailer's website (where the product is sold), contact the manufacturer directly, or review the product packaging.

If you'd like, I can provide a well-sourced comparison of PetArmor vs. Seresto effectiveness, safety, and value based on the available search results—but I cannot fabricate statistics or user feedback patterns to meet the "unique value requirements" without compromising accuracy.
