Over time, fungi species can become resistant to the chemicals in fungicides, and higher rates or more frequent fungicide applications may be ineffective. Worldwide, resistance is appearing in an increasing number of pathogens in field crops, fruits, vegetables, nuts, ornamentals and turfgrass.
Step 2. Take the dog's temperature twice a day in the week before delivery. A dog's normal temperature is 100 degrees F and will drop by approximately two degrees within 24 hours of the start of labor.
When this occurs, expect labor to begin within 24 hours. Once active labor begins and the first puppy is delivered, you can expect a delivery every 45 to 60 minutes. If your dog is having a large litter, it is common for her to take breaks in between puppies. These breaks can last as long as two to four hours.
