Grass and Vomiting. Because many dogs eat grass when their stomachs hurt, it's not uncommon for a dog to eat grass and then immediately throw up. The vomiting could be completely unrelated to grass. It's also possible some types of grass help to induce vomiting and eliminate bad foods from your dog's stomach. In short, the grass may induce vomiting or grass-eating may be more likely with a dog who is already going to vomit. Veterinarians are split on this issue.
A personal reference letter should provide information on who you are, your connection with the person you are recommending, why they are qualified, and the specific skills they have that you are endorsing. It should also include specific examples of times they demonstrated these skills.
According to the APA, these sources should be cited within your work, but should not appear in the reference list since they are considered unrecoverable sources. Create an in-text citation by positioning a set of parenthesis at the end of the sentence that references the interview or email communication. Insert the name of the person, the words personal communication and the full date of the interview or email -- in that order -- within the parenthesis. The person's name should include the first name initial followed by the last name.
