Can a dog become malnourished fast or get sores from sleeping?

Updated on September 23, 2025

Pet's info: Dog | Mixed Breed | Male | unneutered | 4 months and 28 days old | 46 lbs

Is it possible for a dog to go from a healthy weight to a malnourished state within 36 hours? Is it also possible for a dog to develop visible sores on joints from sleeping on a rug and fleece blankets?

Hello! No, since "malnourished" implies that something is missing in either the quality or quantity of food, it is not possible to go from healthy to malnourished within a day or two. However, if an animal isn't drinking, it is absolutely possible to become quite dehydrated in that time.

Yes, mild pressure callouses are common in bony areas such as the elbow where a dog lays down, even if they have some padding underneath. As long as these areas are simply thickened skin, and are not painful and do not have discharge, then they are normal. However, if they are open sores, painful, or have discharge that would not be normal and should be evaluated by a vet. Hope this helps!
