My dog hit her head and has a bump. When should I call the vet?

How awful for you that Buds ran off but I'm glad he came back! There are a couple of things this bump could be on his head. He could have injured himself, he could have an abscess, an insect bite, or he could have a cyst. Given that the bump has down with the ice pack and he is acting his normal self, I would continue to ice the bump for five minutes at a time a couple of times a day for the next two to three days. Should the bump go away completely, you can stop icing it. If the bump doesn't go away, gets larger, he has behavior changes such as lethargy and anorexia, and/or he shows other symptoms such as vomiting and diarrhea, then I would take him into a vet to have him examined. Good luck, I hope this helps!

Ouch poor girl! Yes, I would just monitor her for now. From your description, I don't see any concerning signs. Since she is acting normally, it's fine to monitor her. Should you see any concerning behaviors, then I would take her into the vet. I hope this helps.

This bump could be from an injury, a skin infection, or a growth. The next step is to have Stella seen by a vet since this has been going on for a week. The vet can diagnose what is causing it, and can discuss treatment options with you. I hope this helps.

Your puppy is plenty old enough to get started on her vaccinations, so taking her to the vet shouldn't be a problem. If she's acting fine and the bump is improving, then I wouldn't worry about it too much. She may have just banged herself hard enough to get a swelling. If she isn't acting like herself, then I recommend getting her to see the vet right away.

It is usually cause by hitting the head on something hard or bu an insect bite. monitor it for 3-4 days to make sure the swelling is going down, if it doesn't please take him to your vet in order to get it checked.

First, great pictures and highlighting of the lump! This appears to be a fluid-filled lump. Usually puppies get these when they bang their head on something and then fluid accumulated under the skin. However, I do worry about congenital defects that could cause accumulation of CNS fluid under the skin. If Thor is otherwise acting and looking normal, then either way, it's not an emergency. If he is acting weird, then best to have a veterinarian check him out. If it was just a bump, then the swelling will start going down within a couple of days. If it continues to grow, then it would be concerning enough to make an appointment with a vet. An easy way to detect growth or shrinking is to draw around the edge to the swelling with a magic marker. It will look silly, but it's really easy to tell if the border of the swelling has moved. I hope this helps.

This bump looks like it could be a hair follicle or infection, insect bite, or a skin growth. If it is not going away in 5-7 days, seems to be growing larger, or if it seems painful or itchy you should have your vet examine Yogi.
