I have a 4 week old rescued male flyer that I have had for 1 week. He is on Esbilac puppy formula: 1 part formula, 2 parts water, 1/4 part heavy whipping cream, 1/4 part yogurt. 2 days ago he developed runny poop. I think he was dehydrated, so I gave him pedialyte for 2 feeding then started back with the formula half strength. His runny poop cleared up after this, but now I am having problems getting him to poop. I have slowly been getting him back to full strength formula. Going from 1/2 strength to 75% strength. He has good clear urine output, but the last 3 feeding he only poops a teeny tiny bit. It is light brown and seems to be formed from what I can tell (it is a small amount). After this last feeding I tried soaking his bottom half in warm water while rubbing his belly, with no luck. His belly is a little bloated looking, which I am assuming is from not pooping! Any suggestions, and should I be worried? Does it take their systems a little bit to get back to normal after having diarrhea? Thank you in advance for any advice!!! This is my first flyer
