Can California pepper trees harm my dog? What are the symptoms?

It looks like it could be a California Fan Palm. These are the only palm trees native to California. You can contact the local garden center or Extension Office for confirmation. The seeds/fruit are not known to be toxic, but could cause stomach upset if large amounts are ingested.

The leaf may burn her mouth, but she'd have to eat a lot of them for it to be lethal. She may experience some gastrointestinal effects, such as diarrhea and vomiting, and if these symptoms persist more than 24 hours get her in to see the vet.

According to the California Poison Control system, the Mexican fan palm is not toxic to dogs; however, given that Alister has just started having diarrhea, the berries could be causing him some GI upset, and I would not allow him to eat them anymore. To help treat the diarrhea, withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in his normal diet.

Hello, it looks like that may be a winterberry plant. The toxicity for this plants to dog is associated with vomiting and diarrhea with occasional lethargy. Most of the time, these signs are self limiting, however, severe vomiting and diarrhea should be assessed by your veterinarian. Further information on this plant and its toxicity, as well as other potential toxic plants could be attained from ASPCA Poison Control line by calling 888-426-4435. Call them and describe the plant to obtain more precise recommendations on wether Willow should be seen by a veterinarian today. Hope this helps and best of luck.

The "spikes" of the caterpillar may cause irritation in and around the mouth. Monitor for redness, swelling, pawing, licking or drooling. You may see some stomach upset (vomiting or diarrhea) if one is ingested. One is likely not enough to cause serious toxicity if eaten.

While some pets may not show any symptoms after ingesting tamale foods, there have been cases of fatal poisonings. Symptoms of tamale poisoning may appear a day or several days after consumption, depending on the amounts ingested. Common initial signs include vomiting, diarrhea, abdominal pain and loss of appetite.

Typically you would see pretty immediately signs such as vomiting, diarrhea, abdominal pain, weakness, and heart rhythm abnormalities. You can take Chester into the vet to make sure everything is ok physically, and I would remove the bush from your property and do not allow him access to any. Best of luck.
