The picky little dog usually gets the larger size I break into 4 - 5 bites bites.I've lost track how many bags over the last few years. They smell fine to me, not stale, never unpleasant and being semisoft, they're perfect for her little mouth. They somewhat stick to the dogs teeth so she keeps chewing instead of gulping it down like other types. This simple formulation may not sound like much, but it's a big deal. One of these treats produces a more pleasure, over a longer time, making a much bigger impression on Doggie's brain's pleasure centers, and a firmer association in her memory.I used these treats to teach this (adopted) 7 year-old+ dog 'new tricks' and it was easy.Using only positive reinforcement, she's gone from mistrusting and ignorant, to loving and educated, with no punishment type training and never a harsh word needed.She's not much for chicken. I introduced her to a live chicken, she sniffed at it and ignored it. Not a gene in her reacts to birds and I don't think they smell like food to her. She'll chase a mouse, but ignores pigeons.I've also noted that even when 'I spiced up' her fowl based kibble and she'd eat it, she was listless and tired the next day, but when I switched to beef kibble her energy picks up.She has the treat schedule figured out. Comes home from a walk/ ride, races right to her throne, assumes the "sit pretty" position like a machine and stays there until she gets her due. If I get distracted, 10 minutes later there she is, like a stiff little statute (Look at me! Look at me! Where's my treat?). She'd blissfully eat the whole bag if I'd comply, but I have to watch her weight - so I'm sneaking in the smaller portions.I want her short life to be a happy journey. I'd be content living tending a garden and caring for the creatures, all day, every day, forever an ever - just like Adam was supposed to do. That's my idea of paradise, not being a stock broker/ lawyer/ politician/ banker ... for all eternity.Meanwhile, I recommend these treats. In 60 years of owning and training dogs, they're the best I've found. Every dog should have their day, and a good dog two!
