I have a 13 week old male fawn and switched him to canidae from the breeder provided Diamond about 2 weeks ago. He has been throwing up some food residue from time to time ( looks like taco meat ) usually in the morning. he also poops like 5 times in the first few hours of the day. Is this normal for an active ( if not overactive ) puppy? He has an 8 month old sister ( brindle female ) who plays rough. Any need for concern or is this normal for this stage of life. Thanks, Adam
