Is a rash or bruise on my dog's neck normal after recent vaccines?

Updated On September 23rd, 2025

Pet's info: Dog | Chinese Crested | Male | neutered

We brought my dog yesterday to get his bordetella vaccine and rabies shot. A few hours later he started developing this rash, bruise like patch on his neck it doesn’t seem to hurt him, he’s still eating drinking and playing im just concerned as to why this appeared. We’re going back to the vet tomorrow to make sure it’s ok I’m just wondering if you could give me an answer just to ease my mind a little.

I’m wondering if Friday also had blood drawn for a heartworm test - the jugular vein is often used for venipuncture and bruising can be common. A platelet problem or other clotting disorder could also cause bruising. I think seeing your vet is a good idea.
