I swear that I have a new fear unlocked at least once a month as a pet owner. There are a lot of things to look out for with our furry friends, whether it's a cat or a dog (or whatever you have.)

It's like the time I bought my wife her favorite Stargazer Lilies for Mother's Day, and the cat ended up eating them. We didn't think much of it until we found out that it was highly toxic to cats. (And this was on a Sunday when we had to bring her to the emergency room. After a thousand dollar bill and a couple of days later she was just fine.)

Common items at Minnesotacookouts can make your dog ill. 

Did you know that when you finish your T-bone steak, you shouldn't give it to your dog? Lots of people don't know that. Once the bone is cooked it becomes more brittle, and your dog could harm themselves with sharp bone fragments and chunks that could cause blockages.

Don't ever feed anyone else's dog any food scraps. Period.

You may be thinking you're being nice to the dog, but there are so many reasons why you shouldn't feed table scraps to someone else's dog. They may have sensitive stomachs, allergies, or medical issues you don't know about.

My brother-in-law, trying to get my dog's affection, fed him table scraps and Thanksgiving. That led to a week of doggy diarrhea. Trust me, don't feed anyone else's dog food scraps. Please!
