With attention to a few things, one can have perfectly dog friendly gardens.
Here are a few ideas to try with your dog and garden:
There are nice alternatives to a lawn, but if you prefer to have one, you can minimize the yellow patches that will likely appear, by pouring water over the spot where the dog has peed straight away, which will dilute the urine and the damage to the lawn. For patches that got yellow, cut it out and replace with new grass, whether using seeds or turf.
Most dogs love water so any water garden feature will probably catch his attention. For big features make sure the dog will be able to get out by himself, in case he decides to get in. I once had to rescue my dog from a big water tank in a hotel! Smaller water features might have water that is not drinkable.
With training, most dogs will learn to leave the pond and other features alone. Do make it party time though when you are watering the garden, dogs love to play catch with water and it will be fun for both of you.
Don’t use any chemicals in any water that might come in contact with him or that he might drink. Going organic helps make a garden dog friendly.
If your dog likes to dig, leave a place in the garden free for him, like a small border or a sand box and with some training, get him to change his attention from your flower beds to this place. You can help training by hiding a bone on that place, when he is watching at first and soon it will be his favorite place in the garden. Always give positive reinforcement when he is digging there, so he will learn faster.
Be aware of toxic plants and try to keep it away from your garden or out of reach. Some common plants that are toxic are buttercup, daffodil, wisteria, hydrangea, tomato, yew, delphinium and foxglove.
Sometimes you just need to be careful with some parts of the plant, like flowers or berries, but in other cases like with tomatoes, all parts of the plant are toxic.
Ground tree bark is great, because it will tolerate all. But don’t use cocoa mulch. Be aware of tree stumps and rotten wood, it might grown fungus or mushrooms which might be poisonous.
Usually the more your dog is bored, the worse it will be for your garden… A dog friendly garden has to be an interesting garden, with flowers to smell, wildlife to watch (birds, butterflies, beetles…), things that move with the wind, all of it will be of interest to a dog.
Dogs like to run, so in a small garden if there isn’t a path big enough for that, he will run over the plants. See what/where are his usual routines and take that in account when placing plants in the garden. More fragile plants should be as much out of his way as possible!
With just a few changes you will get a dog friendly garden that will make everyone happy.
