Is anyone having problems with TOTW High Prairie or Pacific Stream canine formulas? I've been feeding it for 3 months+ and like the results. Last night one of my dogs appeared depressed and refused to eat. Tonight 6 out of 15 had diminished appetites and one refused to eat. I'm uncertain about the cause of my problem. It may only be coincidental to opening a new batch of feed in that the dog who would not eat last night ate some tonight. Stools appear normal for the most part. These are mature dogs that have been field trialed up and down the Eastern seaboard so they have probably been exposed to and developed titers to just about everything. I'm leaning toward exposure to some sort of a short term off the wall viral thing that affects the digestive system. They are not febrile nor are they vomiting- not SICK, sick but not quite right. Any ideas?
