My dog sleeps more, seems sad. Is it the new puppy or a vet concern?

I am sorry to hear about your concerns for Archie. Any behavior changes can be a sign of a health problem in a pet. We can have problems such as arthritis making them feel uncomfortable and not wanting to get up and move around like they used to. We can have systemic illness causing them to just feel lousy and therefore not being as interactive as normal (imagine if you have the flu or a bad cold and just feel tired/like you don't want to do anything). For these reasons, I would recommend a visit to your vet if Archie is having changes as you describe in his energy/enthusiasm. The vet can do a good physical exam to check for any abnormalities, and may recommend doing bloodwork to screen for underlying diseases.

At 3years of age he would generally expected to be more active but every dogs character is different and some are very placid. If his behavior has changed over the last 3 months I strongly recommend a full health check by your vet to rule out medical or painful conditions which may be reducing his mobility

Thank you for submitting your question regarding Moxie. I think that her sudden change in behavior is worrisome. Dogs can slow down as they age. However, she is only middle aged. Plus age changes are gradual. Not as dramatic as you have described. I recommend that she sees a veterinarian. I worry that she is painful somewhere. For example, neck and/or back pain is common in small and medium breed dogs. Arthritis or a soft tissue injury could also explain the signs you are seeing. The veterinarian will carefully examine her. X-rays may be recommended. Based on these results, treatment can be started to help her feel better. In the meantime, keep her quiet and do not give any over-the-counter pain medications as these can be toxic to dogs. I hope this information helps!

Thanks for using Petco Pet Education Center, formerly Petcoach! Lack of energy can be the sign of many things that go from just being tired to actually representing a problem like due to pain for example. If he is otherwise fine, I recommend you keep a close eye on him for now. If there is no improvement within the next 2-3 days, have him evaluated by a veterinarian for further assessment and treatment. Good luck and have a great day!

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. Cornelius may be tired from the trip indeed. Other common causes of lethargy in a puppy include fever, ongoing infection, abdominal or musculo-skeletal pain and more. As long as Cornelius had something to eat and drink and is resting comfortably, you should monitor him at home. However, if he is still lethargic tomorrow morning, you should take him to your local vets for an appointment.

This can be caused by many different things, including impending illness, stress, pain, a change in his environment, behavioral, etc. I would recommend a good checkup with a vet to see if there is a medical cause. The vet will perform a thorough physical exam and look for any abnormalities or sources of potential pain. Bloodwork may be recommended to for internal medical illnesses. If nothing is uncovered, then they may discuss other treatments such as things for stress or help you evaluate what started this new attitude.

I'm very sorry Sadie isn't feeling well! I can understand they you might be worried, but it is a good sign that she is eating every meal and drinking water. Lethargy is a very general sign of illness, and it can be caused by many different things such as systemic illness, infection, injury, or inflammation. I would monitor her for now, and if she is still lethargic in 24-48 hours, I would take her into the vet for a health check.
