Pet's info: Dog | West Highland White Terrier | Male | neutered | 1 year and 2 months old | 20 lbs
Hi, My dog is acting very lethargic today and he is normally full of energy. He has eaten and gone to the toilet but it far sleepier and docile than usual. He hasn't eaten anything bad to my knowledge and I can't find any ticks on him. My vet is closed but did not want to contact emergency vet unless it was an actual emergency. He has been recently neutered but wound is healed and He had a two week check up and said all was fine. I am just worried as very out of character for him to be so tired

Thank you for using Petco Pet Education Center, formerly Petcoach! Loss of energy is definitely cause for concern as it can be caused by many conditions. I recommend keeping a close eye on Peter and having him seen by a vet if this continues, or you notice that he is losing his appetite, vomiting, or having diarrhea.
