🔍 How to Choose the Best Probiotic for Your Dog

1. Look for Multiple Strains

More strains = broad­er diges­tive sup­port.
Com­mon help­ful strains include:

• Lac­to­bacil­lus aci­dophilus
• Ente­ro­coc­cus fae­ci­um
• Bifi­dobac­teri­um ani­malis

2. Check CFU Count (Colony-Forming Units)

Best range: 1–5 bil­lion CFU per serv­ing.

Too low = inef­fec­tive
Too high = may cause gas at first

3. Avoid Unnecessary Additives

Skip for­mu­las with:

• Arti­fi­cial col­ors
• Arti­fi­cial fla­vor­ing
• Excess fillers
• Sug­ar

4. Consider Your Dog’s Preferences

• Chews → picky eaters
• Pow­der → mix­es eas­i­ly
• Cap­sules → high­est puri­ty

🐶 Common Digestive Issues Probiotics Can Help With

Pro­bi­otics are effec­tive for:

• Loose stools
• Gas & bloat­ing
• Bad breath
• Occa­sion­al vom­it­ing
• Food tran­si­tions
• Stress-relat­ed stom­ach prob­lems
• Poor stool qual­i­ty
