During my time as a zoo keeper I learned many things about animals. For instance...
All of these behaviors are ways the animals learned to pass the time. To keep our accreditation, and to be kind responsible caregivers, we were required to provide the animals with a variety of daily enrichment. Enrichment was anything that stimulated the animals senses and encouraged them to use their mind and body in ways they would living in the wild. This could be food, toys, puzzles, scents, different textures and ground covers, novel sounds or training activities. It was fun seeing how creative we could be.
Without this stimulation animals can easily develop stereotypic behaviors which result from boredom and stress. This is the tiger you see pacing back and forth, the monkey rocking side to side, or the porcupine that won't stop scratching at the corner of its enclosure.
We now understand variety is necessary for our zoo animals, but many people think its fine to keep their dog inside all day with one squeaky toy and a 30 minute walk. We provide Fido with meals, a warm bed, and the pleasure of our company 12 hours a day and they have the poor taste to bark, dig in the yard, chew our shoes, jump on the furniture, and knocking over the lamp while trying to catch their own tail.
These dogs more than likely are bored out of their skulls and have more energy than they know how to deal with. Their little living room enclosures don't even have hourly guests coming by telling them how cute and exotic they look. Its our job to give our dogs some hobbies or even better work to be done to earn their room and board.
Exercise
We all know I think exercise is essential for a happy dog (and a happy person). Its an opportunity for dogs to get their hearts pumping and to see new places and smell new smells. Aside from just walking and running there are a multitude of canine sports such as agility, flyball, lure coursing, hunting trials, dock jumping etc. There is also just getting out and playing with your dog. Fetch, tug of war, running around the yard like crazy animals all sound fun to me.
Training
It is a great thing when you can teach your dog how to learn from you. You can encourage all the behaviors you want from your dog and help them love doing it. When I'm shaping a behavior my dogs get very excited running around the room hoping to hear a click. Training allows you to mentally and physically stimulate your dog. My dogs do the majority of their training in order to earn their daily food allotment. Instead of their meal being 1 minute of gorging followed by 23 hrs and 59 minutes of wishing they had more, I spread their meal between several training sessions fed out a few kibble bits at a time.
Food
Special treats or clever ways to feed your dog can really brighten up their day. If you don't want to take the time to feed your dog through training you can at least find ways to make eating an exciting challenge. You can scatter their food around a room or yard and make them sniff it out. Put their food in a paper bag, milk carton, box, or other interesting container and your dog shred his way in.
My dogs love gnawing on carrots, squash, yams, green beans, and apple. I often give them my cut off carrot tops to munch on for a bit.
One of our favorite treats at the zoo was making "Popsicles." We would get blood or water and freeze a variety of meats and treats inside. We froze kibble, hamburger, fish, veggies, crunchy fruits, and other treats inside. I am sure most of you at home don't have access to buckets of blood, but my dog's kibble added to hot water makes a delicious stinky fishy mess that the dogs love. I have also seen bullion used, but I would be careful of high sodium levels and onion flavoring. You could make you own stock from simmering the bones and meat trimmings left after your chicken dinner. Just make sure you don't feed your dog cooked bones. You can freeze your concoction in their dog food dish, miscellaneous containers, or cupcake pans. I wouldn't suggest feeding these to your dog on the living room carpet.
You can also find devices that release food to surprise them throughout the day.
Toys
There is an endless list of dog toys. They can be used for training, partner games like tug and fetch, alone like when my dogs eviscerate fuzzy bunnies and happy stuffed squirrels, or used as puzzles to contain food like Kongs which can double as chew toys. You can make your own toys with customized fillings if you have any old tube socks. Just put what treats or toys you want inside a knot the top. Little fox puppies loved swinging them around and playing tug with them.
I had a dog that carried around an old flat leather football for 10 years. When I worked in a greenhouse my dog loved chasing, shaking and tearing apart dirty clumps of roots and grass and would chase then eat miniature pumpkins and squash. They also loved chasing after and ridding our yard of as many grasshoppers as possible.
There is an almost unlimited variety of items for your dog to chew on such as Nylabones, rawhide, bully sticks, antler, smoked bones, pig ears, special aged cheese, filled treats, hooves and more.
Smells
One thing I will never forget from the zoo is tigers go crazy for old lady perfume. Spray some around and they will roll around and rub their head and neck against smelly objects until they smell like they are ready for church. I have seen my dogs perform this same behavior on a pair of my stinky sneakers. You can make old toys, boxes, spots in the yard, and other object you may choose new and interesting by experimenting with safe smells. Perfumes, juice from a can of tuna, urine and scents used to train hunting dogs, stinky socks, items that belonged to other animals, raked up leaves, new mulch, freshly turned soil and many other things can really excite your dog. My dogs go crazy and rub the floor for smells whenever I use Bag Balm for dry foot pads.
On occasion, when I'm ready to clean up a mess, I let my dogs tear apart empty boxes that used to have food in them. Even smells that make your dog curl his nose and huff away add interest to the dog's day, so don't be afraid to experiment a little. Just remember if a smell seems strong to you its even stronger to your dog so no need to over apply.
Sounds
The abundance of squeaker toys should make it obvious that dogs love toys that talk back. You can by packs of squeakers if you want to add them to your own homemade toys. I have also found toys with a crispy crunchy plastic inside. One of my dogs likes crunching on empty soda bottles with the lids removed. You can also find toys with speakers inside that make a variety of animal sounds.
My dogs also like to sing along when I play the harmonica or trumpet.
