Hello and thanks for using Petco Pet Education Center, formerly Petcoach! I'm sorry to hear that Lyla is not herself! I think it would be a good idea to take her to your veterinarian. There are many things that could be causing these signs in a younger dog (gastrointestinal disease or parasites, infection, heart worm disease) so I think it's very important you have Lyla examined. Good luck and I hope Lyla is feeling better soon!
