Very small 12 oz chihuahua puppy. Breeder fed Royal Canin puppy and canned puppy food. I have had her for 1 week. She was eating her food, with water added. Now she doesn't like it. Also having trouble getting her to drink water. I finally used an eye dropper and she is talking water from that. She is just 2 months old. What over puppy food is best for her breed?

Thank you for submitting your question regarding Mystic. Being such a tiny puppy, she may have difficulty regulating her blood sugar. If very young small puppies go too long between meals, their blood sugar can drop too low. This results in a weak lethargic puppy that will be less interested in eating and drinking. You can try using a supplement known as NutriCal to keep her blood sugar up. If she seems unresponsive, place karo syrup on her gums and seek immediate veterinary care. Otherwise, leave puppy food available at all times so that she does not need to go extended periods between meals. Continue this until she is around 4 months of age. As far as another puppy food option, I would use a small or tiny breed formula from Purina or Hills. These are trustworthy companies with products backed by extensive research. You can add warm water to the dry kibble, mix canned and dry food or just offer canned. You may have to try different combinations to see what she likes. I hope this information helps!

    Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Bella is adorable! If she is lethargic and not acting herself I recommend taking her to a Vet. If she is acting otherwise okay then I would try a different brand of puppy food, get canned if you have been feeding dry and dry if you have been feeding canned. Try some meat flavored baby foods. I would also have a stool sample checked for intestinal parasites as that is a common cause of problems in small breed dogs. If none of the above works she needs a Vet exam. Toy breed puppies that do not eat are at risk for low blood sugar which is life threatening. I wish you the best!

I just got a puppy he’s about a month & a couple of weeks. This is my second day with him. But I’m worried he doesn’t eat ask much. I give him the milk for puppies I give him soiled food I crush it up for him but he doesn’t eat. What should I do? Is
Poor Chico. It may be that he is away from his mom and littermates. He may also not be use to the dog food over his mother’s milk depending on his age. I would continue to offer him the dry and canned puppy food. If he isn’t eating it you can also try some plain chicken (no bones) and white rice. If he doesn’t eat anything, I would be sure to put some Karo syrup or nutrical in his gums to prevent a low blood sugar. If he continues to not eat, lethargic (never playing) or any other symptoms, I would have your vet take a look at him. Your vet will be able to do a fecal and even blood work if needed and get him started on meds if needed. I hope this helps!

What is the best puppy food for a 2 month old puppy? Because my puppy is not eating and always drink water instead
Brands of puppy food I recommend include Royal Canin, Hill's Science Diet, Purina ProPlan, and Iams. There could be a medical reason why Shabby isn't eating, so I do recommend a check up with the vet today to make sure she is healthy. Best of luck.

Hello, my dog is a very picky eater. I am feeding him with Ziwipeak air dry dog food, and from what I heard from reviews dogs usually love this food. Some owners even use it as a treat, this is how good it is. However after a few days of eating this
You're definitely on the right track with thinking that puppies as tiny as Norik need a reliable and regular feeding schedule in order to prevent hypoglycemia (low blood sugar), so it is important to find a food that he likes. I think it's important to be sure that medical problems that could potentially be affecting his appetite should be ruled out, especially if there are other symptoms (occasional vomiting, diarrhea, or other) that may indicate a parasite infestation or other problem. It's fine to try mixing in a bit of baby food (avoid recipes prepared with onion and garlic) or even a high quality canned puppy food (Royal Canin makes some good foods for puppies) to see if this stimulates his appetite. I have 2 small breed dogs and I have always had to feed a mixture of dry and canned to get them to eat. Also, I would consider maybe looking for a food that is specifically formulated for the nutritional needs of puppies. Ziwipeak might be a great adult dog food, and it's likely form

My dog is a mix of a Maltese and Jack Russell...she is about two weeks now..I have a problem in feeding her dog food because she doesn't like it...she normally only drinks milk and water and ultimately eats some of her dog food only when she is left
This is a common problem in small breed dogs. They can be stubborn when it comes to dry food. I would stop offering her milk as this can upset her tummy. You could mix in some canned food or boiled chicken with her dry food to see if this helps to entice her to eat. If so, slowly start to decrease the canned food until she is just on dry food. And you may have to just be more stubborn than her. If she is continuously refusing the eat or not acting right then I would take her to your vet to ensure everything is okay. If she is skipping meals and she weighs less than 5 pounds then I would supplement her with nutrical (high calorie vitamin supplement) to help prevent her blood sugar from becoming too low. I hope this helps!

We have an 8wk old chihuahua going to the vet on the 15th but we're concerned she isn't eating enough dry dog food to sustain her when she only eats a few bites. Is a small amount of meat flavored baby food ok?
I can certainly understand being concerned about your puppy not eating enough. It's really not the best for for your puppy, as it's not formulated to meet her nutritional needs. It's not something that is recommended to give to a puppy on a regular basis, usually only when the animal is sick. In addition, there may be ingredients in the baby food that is not safe for her to ingest. It could be that she isn't used to dry dog food, and you can try making a puppy mush for her to see if that helps. I would soak a high quality puppy formulated dry food in warm water until soft. Then mix that with puppy formula such as KMR to make a mush the consistency of oatmeal. Over the next two weeks, gradually increase the amount of dry puppy food and decrease the amount of water and KMR you use until she is eating the dry puppy food only. If she still doesn't want to eat much, then I would have her seen before the 15th.

I have a new dog and her breed was pomshitz which is a mixture of pomeranian and shitzu. She's still 2months old and she doesn't eat dog food and she also doesn't drink water that much but we forced her to drink milk since we were worried that she wo
Congrats on your new puppy, Honey is very cute! No, it is not right to feed her milk, especially cow's milk. Dairy productions should never be fed to dogs due to GI upset, and milk alone is not a balanced diet for a puppy. It will not be providing her with the nutrients she needs to grow properly. Puppies need higher amounts of protein, calories, and calcium than adult dogs, and a puppy formulated food will give that to her. It may be that she isn't used to puppy food yet, and I can give you a method to try to get her used to puppy food. To help her get used to puppy food, I would soak a high quality puppy formulated dry food in warm water until soft. Then mix that with puppy formula such as KMR to make a mush the consistency of oatmeal. Over the next two weeks, gradually increase the amount of dry puppy food and decrease the amount of water and KMR you use until she is eating the dry puppy food only.

Hello i just got a 8 week old shih tzu i cant get him to eat or drink anything im using the same food products he was being fed before i got him
Thank you for submitting your question regarding Bleu Smith. I recommend that he see a veterinarian today. The stress of a new home and environment can cause a low appetite. However, so can illness. Being such a young puppy, it will be easy for his blood sugar to drop too low from not eating. I recommend placing some karo or maple syrup on his gums and seeking care I hope this information helps!

Older Chihuahua will not eat or drink.
I'm sorry that Tiny is not feeling well. If this has just started today and there are no other symptoms of illness, you could try enticing her to eat with some plain boiled chicken and white rice or with the canned version of the diet she is already used to eating. If she doesn't start eating and drinking in the next 12 to 24 hours, I would recommend getting her to your regular veterinarian for an exam. If this has been going on for more than 24 hours at this point, especially if she's experiencing vomiting, diarrhea, or lethargy, I would recommend a vet visit as soon as possible. Small dogs are especially susceptible to low blood sugar and dehydration if they don't eat and drink for extended periods of time.

Hi, I have a one month old shih tzu puppy and we bottle fed her because the mother dog doesn't always have a milk. But now she doesn't want to drink in the bottle anymore. We are a little concerned because she hasn't eat today. But she is energetic.
You can try mixing puppy food with a little water or puppy milk replacer and see if she is interested in eating. Intimidated to offer the bottle. If she won’t eat or drink anything, I would recommend that you have her examined by the vet to see what could be going on.
