Why does my old dog have painful sores and seem lethargic?

Poor Rocky! He could be biting his tail and unable to poo because he has impacted anal sacs preventing him from passing feces. I see that he isn't neutered, and unneutered dogs are prone to anal tumors, which would also interfere with him passing feces. Finally, he could be biting his tail because he's suffering from fleas. Rocky has to see a vet for this, as it's quite serious he's biting his tail so much it's bleeding, he's yelping in pain, and hasn't pooped in two days. I can give you some resources that may help you afford a vet. You can see if your vet accepts payment plans, if there is a low cost clinic in your area, or you can apply for Carefree Credit online. http://www.carefreecredit.co.uk https://www.rspca.org.uk/whatwedo/vetcare http://www.easipetcare.com I hope one of these resources helps you, please take Rocky into a vet asap.

Poor guy. Unfortunately, lethargy and shaking can be caused by a number of conditions including: toxin ingestion, severe anemia, sepsis (infection in the bloodstream), an electrolyte imbalance, or a neurological condition just to name a few. If Rocky is acating abnormal in this way and doesn't seem to be snapping out of it for more than 30 mins or so, then its best to take him to your local ER vet for further evaluation. Please also check his gum color to ensure they are still nice and pink. Pale gums are cause for an immediate vet visit wtihout waiting for the pet to improve. I do hope that Rocky's condition imrpoves soon! Best of luck and take care.

Poor Rocky. He could have a problem with his prostate, may have leptospirosis, a UTI, or bladder stones causing this. He is very sick and he needs to see a vet immediately. Please take him into one now.

This could suggest a recurrence if the cancer or of a different kind of cancer. This would not necessarily be seen on bloodwork. I would suggest you have your vet perform imaging or possibly a CT scan to rule out any cancerous masses. In the meanwhile antibiotic therapy may be warranted to prevent infection of the wounds.

Poor Rocky! Yes, I would take him into a vet as being in pain isn't normal for a dog of any age. Especially since he has been in pain for a couple of days, this is something that needs to be seen right away. It could be he was injured playing with your other dog, but there could be another problem causing his pain such as pancreatitis or a prostate problem. Please take him into a vet right away.

I would recommend taking Rocky in to be examined by your vet as soon as possible. I am concerned that he has either an infection in his testicles or prostate or that something more serious, like cancer, may be going on. Best of luck. Thanks for using Petco Pet Education Center, formerly Petcoach.

Hello, sorry to hear about Rocky. It sounds like he could have back or neck pain. Other signs may include walking very gingerly, carrying his head low, avoiding stairs and not moving onto furniture, and yelping/crying when being picked up. You should rest Rocky until he can be seen by his veterinarian. This is done by keeping him restricted in his crate, not allowing him to jump or use stairs, carrying him to go to the bathroom but then bringing him back in and do not allow him to run or play outdoors. Use a harness in the meantime and avoid neck leashes. Hope this helps and best of luck.
