If not, you should switch to a different kind of dog food that can provide for this requirement. This is particularly important for senior dogs as they are more prone to stomach disorders particularly constipation. As a dog ages, the internal system also begins to slow down.
Best Answer: You can mow when the grass is wet. It will cause the mower to clog up allot more and the clippings will be clumped together. You will most likely have to rake after you finish if want a good looking lawn. It is best to wait till the grass is dry.
Lightly water the complete area, you will want to do this daily for the first couple of weeks (assuming you have no rain). After that, water lightly every 2 to 3 days. Basically you don't want the ground drying out. Once the grass is 4inches (100mm) high or higher, it is ready for its first mowing. Personally, I would mow to a final cut height of 3inches (75mm) or higher. The higher the better IMHO. You don't want to mow Annual Ryegrass too short, especially in your part of the country (warm and humid)...
