Hi , My GSD Daina is almost 4 months old. She has had her last de wormer from the breader. My issue is , is the odity that atfirst her stool is Hard then instantly soft midstream of the stool. I switched her off the Diamond puppy formula a week ago and she is now on the Evo Protien formula. She is growing fine. and Not showing any signs of malnuritment. Just kinda flustered. Also as far as potty training she has been doing great. Now all the sudden after last nights obediance courses at the local pet supplier she has stopped telling me that she has to go outside. I am kinda worried.
