so senor chubby has been on fromm puppy gold since we brought him home with no real issues at all. About a month ago his food increased but then came the runny and horrible amount of water from his eyes all the time...i decided to switch him to FROMM four star but food has not showed up (another long story) and had to pick up new food, taste of wild (grain free, when puppy gold was not grain free) from local store as they don't stock any FROMM, and his tears have continued to pour down but is normal. His new fromm should be in tomorrow (chicken a la veg) and will be starting new food...I know not to put him on grain free without the allergy but that is all they had, and I know switching food like that without transition is horrible, but had no choice as I ran out of food....how long should I give it on his new food to notice a tear satin difference?? I ordered five lb bag in case it doesn't sit well with him...the weather has changed here in new england and the weather is real hot so don't know if that could be causing any of this. I just feel bad because his bright red face (around eyes and tear stains) cannot be pleasant for him. thanks everybody for any advice
