Polly-Os string cheese
I prefer to give raw chews because they are healthy, clean the dog’s teeth and are fully digestible. Make sure to supervise just in case though!
Tripe (smells AWFUL. Ten times worse than bully sticks. But supposedly really good for dogs and they love them)
Beef trachea (you can fill these with peanut butter, sweet potato, pumpkin, etc. and freeze to last longer)
A crate cover can help your dog calm down, like putting a cover on a birdcage. An old sheet works just fine, but if you want the cover to be pretty…
Tug toys (DIY)
I use the freestanding ones and they are really easy, but whatever kind of gate you like and works with your home decor is fine!
The retractable pet gates are cool because they are inconspicuous when not in use, but I’d recommend getting a pro to install them.
