Hello, I am new. My question is ... When does the puppy's ears stand up. Fritz's left ear is 90% there, but his right ear is 25%. How long should I wait? BTW, he is 10 weeks, 18.5 lbs. Also, the vet recommended Royal Canin, but I have him on Blue Wildnerness puppy which has more protein. Is more protein too bad for a puppy?
