We added Bruno to our family on Christmas Eve and the breeder I got him from

had his first set of shots done and dewormed. I followed up with my vet to have a

fecal done and puppy wellness check for my own sake and Bruno’s. No parasites in stool “GREAT” and at 7 weeks weight was 8lbs 5oz. He’s eating and drinks a lot of water. My concern is his stool which is very loose. I did switch him from Iams puppy to Blue Basics puppy with Turkey and potato. He’s been eating this for over a week and figured his tummy would adjust by now but it hasn’t. My vet gave me a probiotic to give him for 3 days but no improvement. Bruno is playing, eating, etc so I know he’s not sick but when will the stool become firm? Also, when he sleeps his breathing sounds at times like his nose is congested and has slight green drainage. Temperature was taken at the vet and was normal. Is the nasal drainage normal? It’s not a constant flow but has me concerned. Any info you have to help ease my mind would be greatly appreciated!
