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:

  1. Always keep the electrode moist when not in use by placing it in an electrode storage solution (3M KCl).
  2. 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. 
  3. Remove the electrode gently from the storage bottle and rinse it with distilled water before use.
  4. 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.

Fun to fetch
Size: 5 Inch, Color: Red, Size: 5 Inch, Color: Red
Perfect size for my 1 yr old Cavapoo that is ball obsessed. This ball is fun to toss around in the yard to exercise and wear out my energetic boy. Perfect for after my work day when I don’t have the energy to match his energy level. He gets to run and chase and I can enjoy his playtime too. Overall the ball is durable and I have confidence it will last for a very long time. We have 2 sizes, small and medium, for my 30 pound athletic pup. He enjoys both equally.

Dog loves them
Size: 6 Inch, Color: Independence Day
My dog loved the first ball I got her, so I got her a second one. Both hhavr been very durable (she likes to puncture things with her teeth). I left each ball slightly deflated, so they were still firm, but she could bite them without issues. She has not punctured either ball yet. I did have to watch her because she started trying to chew the tabs off because she was bored. She has not chewed one off, just started thinking about it, and did a tiny bit of damage to one tab. She loves these balls. We have played tug of wat with them too, so yhe tabs are sturdy, and so is the ball. The dog did not care what collar she got, so I grabbed the least expensive one, and the 6 inch. She is a medium sized dog with razor teeth, and these work great.

Not recommended for the aggressive player..
Size: 6 Inch, Color: Red, Size: 6 Inch, Color: Red
First this ball was not delivered when it should have been. Second, the tabs are poorly made. One day of my dog playing with it and the tabs are already torn up. The ball itself is fun for her and has not deflated for now at least.

Tough little toy for super chewers.
Size: Shoes
Great my two Yorkies. Bought two. So far, still in one piece. UPDATE: This toy does not stand up to being washed. Since it is a "material" and not rubber, I would advise against buying it if you wash your dog toys. Sorry I bought several.

Not a durable toy.
Size: Drop Ball, Size: Drop Ball
I was very disappointed in this rope toys. It took one day for my Border Collie to destroy it. The rope is not a durable material at all. I had a rope toy that was like this one several years ago, but it was much more durable. It lasted a couple of years. I think this one would be great for a small puppy, but not for an adult dog. Very disappointing!
