Two books
One book for people who live with a Golden Retriever. One for everybody else. Both are PDFs, both arrive by email in a minute, and both are made to be printed.
For every dog
Why Most Dogs Die Earlier Than They Had To
He takes the stairs one step at a time now. You said he is getting old, and the matter closed. Forty signs owners read as age, what each one usually means, and what to do about it.
For Golden Retriever owners
Fifty Behaviors and What They Really Mean
He rests his head on your knee. He carries one sock from room to room. Fifty behaviours, one to a page, each in three short parts: what you see, what it means, and what to do.
Barkspective is a YouTube channel about dog behaviour — why dogs do what they do, and what they are saying while they do it. The books grew out of the questions that kept coming back in the comments.
