Update: Lump after rabies vaccine. Just how big?

[Joanne ~ Spud*]

Several weeks ago  Spud had his rabies vaccine and a Bordetella.  I know it is common to have a lump at the injection site but we have a huge mass the size of my hand.  Alarmingly large.  No joke, it must be 5 inches wide, 3 inches high. 

You can actually see the swell when he walks toward me. One side is much larger than the other.

It does not seem painful to touch although I have not tried to aggravate it too much.  He is eating and drinking and plays.

So I know others have had injection site lumps, how big does this get?  Or how big would you allow this to get before wondering if this is normal?

It is not a marble size or an egg. I'm talking sandwich size

 

Update:

Most probable cause is a post-injection site reaction.  Maybe because he was doing a doodle sit pose during the shot and the shot was injected rather low ( almost to the fold of his hip and groin area)  For me, this happened rather late if it is a reaction.

He has no fever, eats, plays, but does favor that area and will get up slowly or run funny almost like a hip dysplasia run. Understandable considering.  He doesnt lick or bother the area.

Steroids injection given to see if some of this inflammation will go down.

At this time, I am going to stop reading the internet about incidents of Sarcoma post Rabies Vaccinations and go enjoy a day off

Thank you for being out there and listening. 

If I hide, he wont see me here.

Hugs from my Dad

I don't know. Maybe you could just call your nice vet for reassurance.

I felt it a few days ago and thought it was a tight muscle. When I came  home from work today, it was massive.  Of course, I will get him to a vet tomorrow first thing.

Just wondered if the post injection lump common after vaccinations should ever be so large?

[F, Calla & Luca]

Good decision. Read the third paragarph:

I don't know, but think it sounds very big for an injection site and especially one that came from a shot three weeks ago. I am glad he is going to the vet. Keep us posted. Give Spud a hug from us.

That sounds super huge.

I wonder if the liquid / fluid from the injection did not really go in, and stayed right under his skin creating the fluid filled bubble? I hope he is OK....

[F, Calla & Luca]

No, that doesn't reallly make sense since the volume for the injections is not very much at all.

[Donna K & Quincy]

This does sound like something more than the usual bump you would get from an injection. A trip to the vet sounds like a good plan. I am surprised that something that large doesn't seem to be bothering him. Does he have a fever?

[Leslie and Halas]

That does sound pretty strange. Glad you're getting him in tomorrow. Let us know what the vet says.

[Karen, Jasper and Jackdoodle]

Ditto this. I hope it's nothing, but I'm glad the vet's going to look at it. 

[Jane, Guinness and Murphy]

I'll be anxious to hear what the vet says....good luck.

[Joanne ~ Spud*]

We are here now. I'll update later

[F, Calla & Luca]

Thanks. Good luck Spud! I hope it's not antibiotic time.
