Can you give your dog claritin not claritin d for allergies?

I'm not a vet, but I would say don't EVER give a dog any medication of any kind without clearing it with a vet. Dogs do NOT have human physiology.

If for no other reason than the dosage is too difficult to calculate based on the dog weight in kilograms, etc., leave the prescriptions and medication choices to the veterinarian. If given too much, it can cause all kinds of problems for your dog, especially depending on the size of the dog. Contact a vet.

Cats and dogs can and do take claritin for allergies but it is still best to talk to a vet first to determine the best dosage for your pet and possible interactions your vet might know about concerning your particular animal.
