Do Dogs Get Lethargic After Shots?

Getting vaccination shots is important to helping your dog say healthy and protected. The vaccination administration involves small doses of the infection to prepare the immune system for future purposes.

However, the shots come with certain symptoms, and your dog may be experiencing that.

Do Dogs Get Lethargic After Shots?

As a result of introducing controlled doses in the vaccination, some symptoms of having the infection or disease may still show. So, yes, dogs can be lethargic after shots.

They may show no interest in taking a walk at their usual times, playing around, or getting involved in any activity at all. Instead of getting worried, you could comfort your dog and wait out for the symptoms to subside in a matter of days.

Will Rabies Shot Make My Dog Tired?

Rabies shots are necessary for your dog (especially if you’re travelling from the UK to oversea) as the virus can be life-threatening once the symptoms are allowed to manifest. So even though it may take a month for an infected dog to exhibit these symptoms, you would still need to give them a rabies shot.

However, the rabies shot is just like any other vaccination shots and may have an adverse effect on your dog. These reactions are always systemic reactions such as lethargy, loss of appetite, and tiredness. The distortion of body functions, however, doesn’t usually last for more than 24-48 hours.

Other reactions from a rabies shot may include:

• Swelling
• Irritation
• Redness of skin

Note, these symptoms are still not fatal, and so you should not get worried when your dog exhibits them.

Do dogs feel unwell after vaccinations?

Do Dogs Feel Unwell After Vaccinations?

Dogs feel sick and unwell after taking a vaccination shot, and it is not something that should cause a scare. So, here are some things you should expect after your dog has gotten its vaccination:

Feeling A Bit Off

This is one of the most prominent reactions you would get from your dog after the vaccination. They might be dealing with soreness and lethargy that is possibly accompanied by a mild fever. If you have not had to deal with this before, it may seem like something that needs the vet’s attention.

Well, these feelings are a product of your dog’s immune system and how it receives the vaccination both locally and systematically. The whole idea of the feeling is to prompt the immune system to react to why the vaccination was administered in the first place.

So, in the future, if your dog comes in contact with such a pathogen again, its immune system would take the necessary precautions. Instead of falling seriously sick, your dog would be totally okay.

Thus, the feeling of lethargy and soreness, but in a matter of days, your dog should be back to its normal selves. However, if the feeling becomes overwhelming, then you could seek help from a veterinarian.

Lumps, Bumps, Swelling

The instant a vaccine is initiated, the skin around the injected area may notice a firm swelling there. It is caused by the irritation and how fast your immune cells are looking to remedy the situation by rushing there.

Even though the lump may seem tender to touch, it shouldn’t grow so much and doesn’t get more painful. However, if it seems to swell even more, then there may be a possibility that your dog has vaccine granuloma.

Ordinarily, these lumps should disappear in a matter of weeks on their own.

Symptoms Of A Cold

Several of these vaccines are given through injections, and others are squirted into their nostril or drops. Since these vaccines are respiratory in nature, the goal is to deal with infections that are gotten through that area.

This is what rationalizes giving a vaccine through the nasal region, so there are symptoms accompanying it. The adverse reaction on your dog’s respiratory tract may involve them exhibiting several symptoms of having caught a cold.

The dogs could start coughing, sneezing, or even get runny and stuffy noses for the next few days. Still, they should resolve in a matter of days, and if not, you should place a call to your vet.

How Can I Comfort My Dog After Shots?

Once the vaccination shots have been taken, and your dog is sick, they would need to be comforted. So, if you don’t know what to do, these points would help you properly warm up to your little one after such an experience:

• Try getting your dog a cozy and warm place to relax after the shots have been taken. Still, don’t get troubled when they decide to sleep someplace else occasionally.

• You can also provide them with unhindered access to water and even their favorite food. Yet, they may sometimes have a small appetite, and it isn’t irregular.

• When you notice that your dog has tried isolating themselves from the rest of the family, avoid any unnecessary interaction. For example, don’t initiate a playtime until when they feel like it or come to you.

• Schedule constant checks on your dog while they relaxed but still don’t try disturbing it or moving it from where it is.

In all, it is crucial that you realize that this type of reaction is not something of concern; with proper comfort, your dog would be as energetic as ever. You could even reward him after such vaccination shots to keep them excited.

How Can I Comfort My Dog After Shots?


When dogs get sick after a vaccination shot, you don’t need to be worried, as is expected. Instead, they may lose appetite, get sluggish, sleep all day or simply show signs of lethargy. These symptoms are expected to subside after a few days.

All you need to do is take the necessary steps to help them feel comfortable and loved during this period. It could be by allowing them to rest uninterrupted, ensuring they sleep in a warm area, and more. So, instead of calling the vet, help them live through the adverse effects.

Note, if the symptoms persist for too long, it is at that point you should consider reaching your veterinarian.
