I should know this after more than 30 years of keeping dogs, but I learned the hard way when Nadi was throwing up for 2 days straight.
Like most dogs, my Shih-Tzu will stare at me no matter what I am eating. I could be eating nothing and just making eating sounds and this is where she would patiently wait presumably until the end of time or she falls asleep.
A friend of mine owns a macadamia nut farm and he gave me a few bags of them to take home. One day I was munching on these (which i don't particularly care for and don't understand why they are so expensive) and of course doggo was sitting there staring at me the entire time. So I gave her a few of them which she promptly gobbled down without really even chewing them.
She loved it and i just presumed that they were ok for dogs to eat.
As it turns out many types nuts are potentially toxic to dogs which is something I was unaware of. I found out that little doggie tummies can not process nuts in the middle of the night when she threw it up on the floor - the nut was almost completely undigested and you'll have to take my word for that because I am not going to post pics of dog puke.
not dead, this is just one of her many resting poses
It took another day before she threw the other one up. It didn't seem to curb her appetite because she was still eating dog food, but also throwing that up as well. It isn't a big deal because it only takes about 1 and a half paper towels to clean up such a small quantity.
I looked online and it said unless your dog ate a lot of them, there is no cause for alarm because dogs are actually quite good at taking care of toxins using their built in defenses.
But i learned a valuable lesson. No nuts for dogs!
You can give them other things though!!
House slippers that were entirely too small for me for example... no problem. She actually wont chew them though, and I am happy about this.
Or you can give them an entire leg of lamb (remnants) that is as long as her body is. She'll be working on that for a while I'm sure!
She will bare her little rice-sized teeth and growl at you if you get too close. I find it really humorous that she believe she could ever hurt anything.
By the way, she has a ridiculous haircut now because I am passing her off as a "mixed breed" on our upcoming flight. Snub-nosed breeds such as Shih-Tzu's are banned on most airlines for some reason but unless a veterinarian is working at the cargo section of the airline, she just looks like any ol' dog now.
