My Chihuahua is underweight. What food helps her gain healthy weight?

Updated on September 23rd, 2025

Pet's info: Dog | Chihuahua | Female | spayed | 1 year and 2 months old | 5 lbs

What food would you recommend for my 5 lb Chihuahua? She is all skin and bones, she has no fat on her but eats so much. I do think she needs to gain more......

I would recommend having her body condition score figured out first to determine if she is indeed underweight. Some pets are just leaner than others but are not considered to be underweight at all. https://www.google.com/search?client=safari&hl=en-us&ei=3essWYH8BcWXjwT5u4agBg&q=canine+body+condition+score&oq=aaha+body+condition+score&gs_l=mobile-gws-serp.1.0.0i71k1l5.0.0.0.53939.1.1.0.0.0.0.0.0..0.0....0...1..64.mobile-gws-serp..1.0.0.tM15jVEPrL8#imgrc=D5srd2kpWBMU1M:
If she is considered to still be underweight then I would try to find out what is causing her weight loss and treating that directly. If there are loose stools then it's best to check her stools for intestinal parasites through your vet.
If her stools are normal, then she may be going through a transient period of not gaining proper weight due to a previous illness. Increasing her current food amount can help. You can also try mixing in a high calorie puppy food for a few weeks. I wouldn't suggest this unless she is otherwise healthy and nothing else seems to help, because a consistent high calorie diet can do more harm (i.e. Pancreatitis) than good in some cases. Best of luck with your pet Layla.
