CARE AND USE
This delicate instrument requires proper care and maintenance to produce accurate, reliable results and to ensure a long, usable life.
Extend the life of your pH electrode in the following ways:
- Always keep the electrode moist when not in use by placing it in an electrode storage solution (3M KCl).
- DO NOT store the electrode in distilled or deionized water, as this will cause ions to leak out of the glass bulb and reference electrolyte. This will produce a slow and sluggish response and can damage the electrode.
- Remove the electrode gently from the storage bottle and rinse it with distilled water before use.
- For long-term storage, always keep the electrode in the bottle filled with enough storage solution to cover the bulb. Replenish the bottle as needed.

Everything a Teething Puppy Could Need — Well-Thought-Out Kit
Size: X-Small, Color: Teething Bone
The Nylabone New Puppy Starter Kit is a solid all-in-one solution for the first few months of puppy ownership. It comes with multiple chew toys and bones designed specifically for teething puppies, and my little one took to them right away. The variety keeps him engaged, and I appreciate that each item is designed to be gentle on developing teeth while still satisfying his urge to chew.
What differentiates this kit from other puppy chew sets on Amazon is the thoughtful selection of textures and shapes. It’s clear these toys are designed to stimulate gums, promote healthy chewing habits, and even support dental care. I also like that everything is non-toxic and durable enough to survive a few enthusiastic chews.
The only reason I didn’t give 5 stars is that the kit might be a bit small for larger breeds, or for puppies that are particularly aggressive chewers. But for standard small to medium pups, it’s a fantastic starter kit that keeps both puppy and owner happy.
✅ Bottom line: A reliable, well-designed starter kit for teething puppies which is thoughtful, durable, and engaging. Makes a great gift for new puppy owners or a practical addition to your own puppy’s toy collection.

Chew

Chicken Flavor Good, But 🔄 Rotation-Resistant✖; Best for Simpler Chewers
Size: X-Small, Color: Ring Bone, Size: X-Small, Color: Ring Bone
🐾 Hi, I’m PVD; plush sophisticate, chew critic, and active curator of rotational toy relevance.
This ring bone and I never fully bonded. I sampled it maybe five times in my entire puppyhood before quietly returning it to the bin (with a single judgmental glance).
Still, it does have value for the right pup.
⭐ Why I originally wanted to love it:
✔️ XS size works well for very young puppies
✔️ Chicken flavor lasts impressively long
✔️ Freezing offers temporary gum relief
✔️ Durable and safe; no odd odors or shredding
🌀 Why it’s now a respectful 3-star chew in my rotation:
✘ Never became a go-to toy (5 uses max in my life)
✘ Ring shape felt awkward, not natural or chic; hard to grip and maneuver
✘ Texture too tame vs. nubs or detailed chew surfaces
✘ When I was smaller, I much preferred the Nylabone Baby Blue Bone Chew Toy with nubs (my personal classic), and have since matured into nightly Nylabone “Nubz” edible bones
This Ring Bone is Best For:
• Very young puppies with minimal chew preferences
• Dogs who like simple textures and circular shapes
• Those just starting enrichment chew play
• Freezer treat rotations (briefly)
🚫 Not ideal for: picky pups, advanced chewers, or dogs who analyze toy ergonomics (like myself).
📝 Final Re-Barks:
A strong, well-made chew, but lacked the intrigue to make my permanent rotation. Works for basic chew enjoyment; not for pups with elevated taste or toy ambition.

Puppy loves it!
Size: X-Large, Color: Teething Bone, Size: X-Large, Color: Teething Bone
My small puppy loves this bone! I originally purchased this for a larger dog, but my small 10 pound puppy loves it more. It’s good quality and a softer material for puppies!

A hit, but could be stronger
Size: Medium, Color: Ring Bone, Size: Medium, Color: Ring Bone
Gave this to my 11 week old pittie, and she did significant damage within 15 mins. She left a pile of chewed bits on the couch but thankfully didn't eat them. Definitely don't leave unsupervised.
That said, she LOVED it and it seemed to help her teething gums so, I'm still giving it a 4/5
