Our almost 3 year old bichon is very lethargic and has not eaten in 24 hrs hours -i just used a dropper to get some warm water down - seems a little better now. She's about 13 pounds, any small dog info?

It could be any number of things. Off to the vet you go.

Definitely contact your vet and see if they will talk to you.

When giving her water, make sure to add electrolytes to it. Sometimes dogs just need a little boost.

Has she been eating and drinking normally before this? Or was she picking? Could be a number of things. But lethargy can be cured 80% of the time with electrolytes :)
