Is it normal for a puppy to have diarrhea after changing food?

Diana Williams: Is it normal for a puppy to have diarrhea after changing their food?

I recently switched my 5 mth old shih tzu from science diet to wellness and was instantly hit with that dreaded puppy diarrhea! Is this the new food and how long will this last?

probably the food. when changing a dogs food, you have to first mix in a little of the new food with the old, and then gradually increase over a couple weeks..feed your dog small amts of the old for three days, then mix in a little of the new and see how it goes.

Answer by Kayteeare

A sudden change of a dog's primary diet can be hard on both their stomachs and their eating habits. Changing your dog's diet should be done gradually and over a period of at least four days (preferably longer).

On the first day of change, you should have plenty of the old dog food left. Add three quarters of their old food, and one quarter of the new food. You should do this for at least two days. After two days or so, add in another quarter, so you have half old food, half new food. Again, keep it at this level for another two days or so. Then add in a third quarter (one quarter old, three quarters new), and finally you can phase out the old food completely.

What happens if you don't do it gradually?
Stomach Cramps
Refusal to Eat

Answer by lissett

Yes, it is common.
What you need to know is that if you are going to change your dogs diet, you need to do it gradually.
It's just like people eating regular food then switching to organic, some get the runs or even stomach aches because it's new food that the body has never dealt with.
Next time, use 75% of the old food and 25% of the new food the first day, and over the next 3 days, gradually add 25% more of the new food until it is all the new food and no more old. If you do this, diarrhea wont come knockin on your puppies back door.

Yes its normal. Wellness is a lot richer and has more meat in it than science diet so it will cause diarrhea for the first few days. You can add 100 % pure pumpkin that you can find in the can to help with the diarrhea. It only takes about a tablespoon per meal to help add the fiber he needs to bulk it up.

    How did you "introduce" your pup to his new dog food? For instance, did you gradually mix the new with the old for a 5 - 7 day span? Or, did you immediately switch over? It's important to slowly introduce a new food, especially to a pup. If your pup is healthy otherwise, then it could very well be the food. Are there any of symptoms - vomiting, loss of appetite, lethargic, etc. I would start out mixing only 1/4 cup (new) to 1 cup (old). Hope puppy adjusts! BTW, Wellness is a good brand of food! :}
