Why does my dog twitch and scratch when I pet his lower back?

Allergies, either to something in the environment or less often to food, would be the most common cause of itching if Charlie is on a prescription flea preventative. He may have a secondary skin infection as well since you are feeling bumps. Mange can cause hair loss but usually isn’t significantly itchy.

It could be that she is itchy. If she is not spayed and is in heat/nearing heat, this can also be a behavior that happens in response. Some dogs may also instinctively scratch or wiggle their tali to the side when petted on the hips or base of the tail. Checking for any parasites such as fleas or ticks on the base of the tail can help alert you to parasites, and if you suspect worms, having a fecal exam done with your local vet can help rule these out.

Thanks for using Petco Pet Education Center, formerly Petcoach! This is possibly due to allergies. It really comes down to figuring out what is causing his allergies so that they can be treated or the specific allergen avoided. A secondary infection is likely and also needs to be addressed. There are many things that can cause allergies though in most cases they can be broken down into 3 big categories: flea, food and environmental allergies. Allergies are usually worked up in a stepwise fashion starting with flea allergies as this is the easiest and cheapest to take care of. If not on a flea preventative, then it would be a good idea to get started on one. If already on one then it would be a good idea to change to something else (there are many new products out in the market). If not improved in 1-3 months then it is time to move on and check for food allergies by switching to a novel diet (new protein and new carbohydrate). If that does not seem to be the issue then you are left out having to check for environmental allergies which require blood and/or skin tests. Allergies can be very frustrating to deal with at first but so rewarding at the end when we are able to treat them effectively!

It sounds like Charlie maybe having an allergic reaction, which is very common in her breed. Allergic reactions can be caused by many things, such as insect bites, food, or environmental allergens. We may not find out what she is allergic to, but a vet can help with the symptoms. Other possibilities can be a skin infection, which also requires veterinary attention. Hope she feels better!

For whatever reason puppies just tend to be itchier and scratch more often than adult dogs. If his skin looks 100% normal where he's been itchy it may not be anything to be concerned about. If you notice him scratching his ears, if there are red spots or hair loss on his belly, or if he seems so itchy that he isn't comfortable you may want to see your vet for an exam.

I agree. If Frankie has never exhibited this behavior before, it could be a sign of skin sensitivity which could be due to several things including allergies, skin mites, flea bites, or other possible causes. You can try adding in an omega 3 fatty acid supplement for dogs, this can help improve the skin health. You may also try changing his diet to something like Royal Canin or Nutro as they are aimed at skin health. Check the skin daily for signs of infection or irritation such as redness or scabs. If these are seen, have him examined by the veterinarian who may prescribe medications. Best of luck and please feel free to post any additional questions.

No he is likely just itchy in that spot. This is no an uncommon response in dogs to being scratched in an itchy place. Especially if he is normal at all other times. I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!
