Welcome to the Q&A Forum

Hello KTW..., I would not make these two pages have the same rel canonical tag, as they are not the same page, nor the same product: http://wagavenue.com/what-happens-in-the-dog-park-pet-id-tag-for-dogs http://wagavenue.com/very-important-pooch-custom-pet-id-tag-for-dogs Yes, they are the same "shape" and made out of the same material, but that would be like an eCommerce site for clothes that was being told they should add a rel canonical tag for all of their cotton T-shirts to combine them on one product page for "cotton T-shirts". That's not a product page. That's a category page. You can have some shared content on product pages about shipping, returns, etc... but if I were you I would invest in as much unique content as you can on each page. Talk about the sayings. The colors. The material. There are a million ways to say the same thing if you're creative. Failing that, you can put the shipping and returns information, and similar templated info, in an iframe or a javascript pop-up window, or some other way of keeping from being duplicate content on every page. Long story short, if you want to rank for 100 different sayings (e.g. "what happens in the dog park dog tag", "very important pooch dog tag") you need to write unique descriptions for each of those. There is no way around it without risking your traffic from Google.
