I have a 10 year old beagle who has recently become ill and I am very concerned. She has been very lethargic, loss of appetite and walks slowly. These symptoms presented themselves over a week ago and then went away, but now they have reappeared. She hasn't been injured and is the only pet we have. She is an inside pet that spends the majority of her day in a crate whil we are at work. We have a spot on the sofa for her and yesterday she was unable to jump up onto the sofa, so I made a bed on the floor for her. I haven't had her to the vet and to be honest, my family really can't afford to take her to one. If you could help, I would greatly appreciate it and your time. Thank you!
