HELP Indian Hawthorn turned reddish brown

Hello:

I wanted to create a hedge between my neighbor's property and my property so we purchased some small Boxwoods and a few Indian hawthorns but her huge dog kept peeing on them and they yellowed and a few died. The few that remained, I've replanted. However, one of the Indian Hawtorns turned a reddish brown after transplanting. I gave it some cow compost, peat moss and lily miller's Vitamin B1 Plant Starter to reduce shock and water it regularly. It doesn't look healthy.

Is it because it is planted by the paver bricks that that lines our driveway. When it rains, the corners do get lots of rain.

What do I need to do. I've spent thousands of dollars on plants, shrubs and grass and I do not want my efforts to be in vain.

Please advise.
