Ten years ago our beautiful older girl was so scared of fireworks we tried a DAP collar. Not sure of the make, but they were new to me and at first it seemed to work. Then she started with vomiting and diarrhoea, was lethargic, unhappy and very ill. Vet couldn't find source of the illness. We genuinely thought she'd reached the end. This lasted for about a month. Then I removed the DAP collar as she didn't need it. Within 48h she was her old self. Suspicious it was the collar I gave her a month and put it on again. Within a day she was sick again.
Fast forward to now. New puppy. Extremely anxious. End of our tether so got an adaptil diffuser. Seemed to help. Then pup got diarrhoea. This made his very snappy and a bit mental. Just puppyness we thought. Then we let him sleep upstairs. We noticed his morning poo was normal and got worse through the day. He was also a different dog at my daughter's house. Suspicious again I switched off the diffuser. One day later and his poos are normal, he's calm and relaxed and like a different dog.
So I'm curious to know if anyone else has experienced adverse reactions from DAP products? Even just loose poo and mad behaviour (we think behaviour was due to having a bad belly)
