If it is a bug bite, the swelling should go down after a few hours. If it does not, I would be more worried about a skin tumor or an infection. Keep Scruffy from licking the area by having him wear an elizabethan collar at all times. Have him examined by the veterinarian if the swelling persists. I hope this helps and please feel free to post any additional questions.

    This is probably an allergic reaction due to an insect bite or a plant outside. those reactions tend to resolve within 48 hours without treatment. if the swelling becomes too large or if your dog is lethargic, take him to the vet in order to get an antihistamine injection.

My dog got bit by something and its growin i need help
If Lila is having an allergic reaction to a bug or bee sting, the swelling will go away on its own within a few hours. It is an emergency if her throat is swollen and she has trouble breathing. If she seems really miserable, you can take her to an emergency vet for Benadryl and steroid injections which take the swelling down pretty quickly.

It seems my dog got stung or bit by something near the side of her face/ upper neck area. Last night when I noticed it, it was a hard swollen mass. I gave her benedryl and it seemed to help lower the swelling and the mass isn't as hard anymore. She d
Hello. A mass as you are describing could be from a bug bite, and if so the swelling should go away in about 48 hours. If the swelling continues past that time then I would be worried about an abscess/cyst/tumor. If it isn't painful or bothering her, and it continues to get smaller then you can monitor it, however if it doesn't go away, gets bigger, gets hard, or becomes painful, then I would recommend you have it seen and tested with a "Fine needle aspirate". Good luck with Bella.

I think my dog has a spider bite.... What can I do
Ouch. The area does look quite swollen and possibly already infected. Depending on the spider that bit Rocco, he may need antibiotics, steroids and antihistamines to prevent the skin from being necrotic (dying off) and systemic bacteria (bacteria floating in the bloodstream which can be life threatening) from developing. i would suggest cleaning it with Betadine diluted 50:50 with warm water for tonight if a vet visit is just absolutely not possible. This will help provide some topical antiseptic cleansing of the wound. Take special care not to get any of this in his eyes. Then getting Rocco seen by a vet first thing in the morning to get this area looked at and treated appropriately. However if a vet visit tonight is possible, then getting him seen right away is best, before it gets any worse. I hope everything works out well for your pet Rocco. Best wishes and take care.

I think my dog has been bitten by a spider or something. I’m not sure. Should I be worried?
It does need medical attention and it very well may be a spider bite or an abscess. You can try to flush the wound and clean it with water and mild soap and apply neosporin to keep it from getting worse until you can get it seen by a vet for stronger medicine

Our hound mix is 8 1/2 years old and has a blistered red skin lesion on his back right flank that appeared about 2 weeks ago. We think it may be a brown recluse spider bite. It is a ring of blisters with a deep center. We have kept it clean and us
The brown recluse spider can produce extremely serious clinical signs shortly after envenomation. These usually include vomiting, diarrhea, bleeding disorders, organ failure, and death. Without life saving measures, typically dogs do not survive. Since this occurred two weeks ago, it is highly improbably that this was the cause of Buddy's recent skin issues. From the picture above, it actually looks like a skin tag but your description is very different. As long as it is not oozing or being a bother (and appears to be healing slowly), Buddy may be on the up and up. The veterinarian can certain perform diagnostic testing of the lesion in order to identify the cause and type of problem if this is something you are interested in pursuing. However, I am not sure that this is really necessary at this time. If the areas starts to become infected, stops getting better, or becomes later, I would definitely recommend a visit to the vet some time soon.

Peewee has a lump in the side of his face that was not there this morning, could it be a spider bite? Should I rush him to the vet? He is acting normal and it doesn't hurt him when I touch it.
Thank you for contacting Boop by Petco with your question about Peewee. Since it doesn't hurt him and he's acting normally, keep an eye on him for now. Should the lump get bigger, starts to bother him, he has trouble eating, becomes lethargic, or anorexic, then I would rush into an ER vet right away. Otherwise, you can wait until the morning to have him seen by a vet. I hope this helps!

My dog has a little lump behind his ear someone told me it could be a spider bite
Spider bites can get pretty large with a dark center and a discharge. They can take longer to heal than other insect bites. There is never a way to be certain what causes it. If there is a drainage then clean it with soap and water and keep neosporin in it until you can get to the vet. If there is no puncture and it is a bump under the skin then I would have that checked to make sure it is not a growth

Wondering what is wrong with my dog. Is this urgent and do I need to go to the vet ASAP? He licks it sometimes but it doesn’t not seem like a big concern for him.
This is probably an allergic reaction due to an insect bite or a plant outside. those reactions tend to resolve within 48 hours without treatment. if the swelling becomes too large or if your dog is lethargic, take him to the vet in order to get an antihistamine injection.

I believe my dog may have been bitten by a spider. My husband found a spider in his cage and now our dog has two swollen bumps under his tail, along with some red patches. He is not disoriented, but it seems to itch very bad. I'm wondering if a trip
Thanks for using Boop by Petco! Poor Chippy! If it wasn't a venomous spider he should be ok. If he's scratching a lot I would be worried he would cause an infection. That would require antibiotics. You can try washing the area with soap and water and make sure it's dry. You can also apply a thin layer of antibacterail ointment. We aren't allowed to give Benadryl dosing so call your vet for how much to give. That may prevent him from causing more damage. Good luck and kisses to Chippy!

What kind of bite could this be and how should I treat it?
That may be a black fly bite. If that is the case, it should not be itchy (normally), should not bother Lily and should resolve on its own without treatment. If the area is becoming swollen, enlarging or appearing to spread, then Lily should see your veterinarian. Otherwise, the areas tend to fade on their own. https://www.vin.com/veterinarypartner/default.aspx?pid=19239&id=7986755 Good luck! I hope that was helpful. Thanks for using Boop by Petco.
