I have two dogs - a male and a female. They pee on or around my plants. I can't say they have harmed anything except the grass. I dust the grass with lime to sweeten the soil.
"If you have dogs, dog urine has undoubtedly damaged your lawn. Dog urine contains ammonia and salts and these are hard on grass. The salts, especially, pull moisture from the grass roots and cause the grass to die. The ammonia causes the soil to be more acidic, which is also stressful for grass. One easy solution is to add dolomite lime to the urine spot. Dolomite lime helps to neutralize the acid in dog urine and restore the soil to a pH balance more favorable to the growth of new grass."

I have hydrangea, bleeding hearts, mountain laurel, Miss Kim lilacs, lady's mantle, alliums, daylilies, peonies, etc. I haven't seen any damage from my dogs.
What kind of sunlight conditions do you have? Is it early morning sun or afternoon sun?
My Miss Kim lilacs were getting too much sun. I transplanted them to a shady morning with bright western afternoon sun and they look much better. Mountain laurel needs the same conditions as my Miss Kims. I had hostas in this area too but they had sun damage.
Morning sun with afternoon shade is great for bleeding hearts and lady's mantle.
If you post your sunlight conditions, it would easier to respond.
