It's reported that adverse effects from metoprolol most commonly occur in geriatric animals or those that have acute decompensating heart disease. Doses as high as 3 mg/lb have been noted and so 25 mg in a 25 lb puppy (1 mg/lb) should be well-tolerated. The most common clinical signs after exposure to this drug were lethargy, tachycardia (increased heart rate), vomiting, and bradycardia (slow heart rate) and it's just as likely that your puppy will remain unaffected. The probiotic is a non-issue but the senna acts as a laxative in dogs just as in people; senna is an irritant of very little toxicity when given as a single adult human dose. There's no need to induce emesis or treat in any manner.Please respond with further questions or concerns if you wish.
