I suggested regular Tabasco sauce to my wife a few months ago when he took apart her slippers and two pair of flip-flops but she nixed the idea because, “We don’t want to hurt him, he’s just a baby and will grow out of it.”
She also lost a twenty year old pair of winter boots about three weeks ago, haha!..
Speaking as a dog owner who learned the hard way: no he won't.
Behaviors which are not corrected in puppy-hood will be set in stone once the dog is adult.
My Zoe probably would have liked tabasco and capsaicin. I know a few things the vet suggested as deterrents, she loved. One time she had suggested lemon juice. Before I put it on, I said to my sister, “Let’s just test this first.” So I put some in my hand, held it out, and “lap, lap, lap” accompanied by sad eyes when the lemon juice was gone.
Back when we had Katie, one of our Dobes, we were having some lemon meringue pie once and she was sitting patiently next to me, willing any one of us to give her some of that delicious looking food. I wish I would have had a video camera to capture the expression on her face when she first tasted that pie. I’ve never seen a dog open their mouth, turn their head, and pucker at the same time. Totally opposite reaction to that of Zoe’s... :-)
Zoe also ate wild black raspberries right off the brambles (as did Max, another of our Dobes from decades gone by), and loved cranberry relish almost as much as turkey and pumpkin. Tucker preferred “gifts” from the ‘food window.’ Both easily recognized the golden arches— and we knew they knew because they’d sit up a little straighter and behave like little angels when in their vicinity... Drive throughs were magical to them.
