We've had a couple of Jack Russels and I will second that statement!
After checking the "net" I don't think this was a copperhead. Too early in the year for babies and I couldn't find a pic of a juvenile that looked the same.
I went out this afternoon around 1pm for a short walk with my 8 year old niece and my 4 year old Akita named Fuji. Got out the neighborhood and entered the park, which was having a wounded warriors bike race also.
After thanking some for the sacrifice they gave for this country. We started into the wooded trail and after about 50 yards Fuji was just off the side of the trail. All of a sudden she started shaking her head like she had been bee stung. I immediately knew what had happened and backed my niece and dog back down the trail. Then slowly eased up to the area where it happened and sure enough about a 2' copperhead was coiled up in the leaves. Looked at the dog and 2 fang marks in her lower jowls. Well that ended the walk, we turned around and headed to the house. Loaded her into the pathfinder and off to the vet. By the time we see the vet, it has been over an hour since she was bit.
Now I grew up in the country and seen a few dogs and cats bitten by a copperhead and most survived. Other then swelled up for a few weeks. Sure enough the vet tells me the same thing gives her some antibiotics and something for the pain, and sends us on our way and to come back tomorrow.
I tell you it's amazing how tough these family members can be. Other then a little swelling you wouldn't know anything was wrong. I'm in more danger from the wife for walking her in the park...lol...No irregular breathing, drooling/foaming, shaking or weak when moving. I'm pretty sure with it being an adult copperhead that she was lucky and got a dry bite. Time will tell but here is a pick 3 hours after the bite. Kinda looks like she has wad of tobacco in her gums but other then that no problems.
We just should have been more careful I know they are there. But normally I see them in the evening on the paved bike trail, or sunning themselves in the morning. Just wasn't expecting one at 1pm with a temperature of 86 degrees.
4. Depth of the fat layer will also slow absorption.
Glad to hear your dog is doing better.
Two things that dogs love to play with....
snakes and porcupines !!
I never understood why dogs go back for more ?
